Good Knife Sharpener suggestions

Sharpmaker
The Spyderco Sharpmaker works very well for their serrated edge models. IMHO the biggest drawback of the Sharpmaker (besides their price) is the cleaning.



Because you sharpen the serrated knives only on the narrow edge of the triangular stones you have to clean the stones regularly or they will clog and not sharpen properly. We used to use Ajax or other powdered cleanser and it worked a charm. However once they went “non scratching” or “fiberglass safe” or whatever it was they lost much of the abrasive and stopped working as well.



I do not use the “V” sharpeners for sharpening near the tip or on non serrated edges as it is too easy to round the tip due to the way the knife tends to rotate as you come off the end.



On the non serrated blades I prefer DMT diamond because they are easy to clean, last virtually forever, and stay flat and you can get the green 1000 grit for finishing up. (being lazy I use the conical model for serrations but it isn’t as good as my needing to be cleaned Spyderco triangular stones)



If I still had a selection of good quality hard oil stones I would use them on my flat knives, but alas they went missing 20 years ago.

Dressing an edge on
power tools is not a good practice for the casual tool user. Its dangerous enough for someone with experience. Personally, I have time to sharpen by hand and keep all of my fingers. (35+ yrs experience using shop tools in my career.)

More like “wicked old” school!

In the interest of full disclosure, I only use Arkansas stones for knives, as they're easy to sharpen freehand. For all my edged tools (planes, spokeshaves, chisels, etc.), I use combinations of grinders, sandpaper, diamond hones and waterstones, with sharpening jigs.

I don't have a translucent stone, but I do have a small "black hard" Arkansas stone that I used for fine polishing on pistol parts.

Nobody uses Chef’s Choice 120 or 130?
The guy at Sports Authority recommended them for the Bench Made and other knives that they sell.

uh, no
At least not me. You listen to a guy at a Sports Authority about sharpening knives the same way you listen to his advice on firearms: grain of salt.



Water stones for me when I want a great edge, Norton Fine India for utility. I use properly maintained straight blades. Serrations, IMHO, are a generally a crutch [with certain exceptions (like Navy units underwater cutting through many very thick aramid lines)]. The sawing action of a serrated blade works even when the blade is relatively dull, this is true. But to my mind, if you are carrying a knife it should be sharp and you should know how to use it (that includes caring for it).

I do have serrated
edges so whether they are good or not, i need to maintain the edges. I was told in H1 the serrated edges have a harder strength on the scale than the straight edge. I like the spyderco sharpmaker but the Lansky is interesting as you clamp the knife down which might work best as i may not be so accurate with keeping the knife straight up and down. I cannot use just a flat stone because of my serrated knives so i am trying to get something that will work with both! Thanks for all the suggestions.

Are Chef’s Choice bad for blades, or
just not your preference, because you prefer to hand hone?

Yes, they’re bad for blades
Most powered sharpeners do a better job of burning the steel than sharpening it. You can do a lot of damage in a hurry with one of those.

There’s no good way to sharpen
serrated edges without specialized files, grinding stones, and/or jigs. In use, the points don’t really do much except, perhaps, help to protect the cutting edges in the valleys. Every maker uses different geometry for the shape and pattern of serrations. I got lucky with my favorite bread knife when I found that the round files I have for my chainsaw and the round ceramic “stones” I have for sharpening carving gouges are a good fit. Still, it takes a good half-hour for me to hand-hone that baby to better than factory sharp, something I do less than once a year.



In practice, sharpening even a plain-edged knife leaves a serrated edge, albeit microscopic. For a utility or river knife, I wouldn’t bother honing beyond anything finer than a medium “India” stone.

My dad, of all people, got me a pretty
fancy Chef’s Choice sharpening machine for my birthday about six or seven years ago. I say “of all people” because he’s wickeder old-school than Nystrom. I guess some folks get a little tappy as they age.



Anyway, I took the thing out of the box, read the instructions, plugged it in and ran a five-inch utility kitchen knife through it quickly and with light pressure. Like Brian said, I was kinda taken aback by how much metal had been removed so quickly. Those little oscillating diamond-encrusted pads sure do work well when new! A little too well IMO.



Maybe they’ve improved them since, I don’t know. I re-gifted mine, brandy-new in the box, to some anonymous picker at the take-it-or-leave-it space at my dump. Probably ended up on Ebay. Don’t tell my dad.

One good reason to fine hone is…

...that you end up with a much more durable edge. While the microscopic serrations of a medium-honed blade cut well when they're new, they're fragile and quickly bend over and/or break off. The finer you hone a blade, the sharper it will stay after the initial use knocks off the finest points on the edge. That's one of the reasons I sharpen my cutting tools to a mirror polish; I don't have to resharpen as often and it takes very little effort.

A somewhat related side note is the same effect is seen when sanding wood. Coarse sanding produces deep furrows and a relatively soft surface. The finer you sand, the harder and more durable the surface becomes. Try it on a piece of hardwood sometime. Sand it with 80 grit, then tap it with your fingernail and you'll get a dull thump and you will easily be able to make a nail imprint in the surface. Continue sanding with finer grits until you get to 400. When you tap on it, it will sound very hard and you won't be able to push your nail into the surface without some effort, if at all.

Nitty gritty and the angle of the dangle
Now you’re getting into edge geometry and alloy hardness. When camping, I take a basic Norton combi stone and a six-inch mill bastard which cover any touch-ups needed. I’m not doing any shaving or field surgery. I haven’t had my PFD knife out of its scabbard in years but, to slash a line in a hurry, I’d choose the side with serrations first.



That said, I’ve handled Japanese blades that haven’t been honed in over a hundred years that I think might still split a hair or hack a slave in two, so sure, a polished, perfect edge has advantages.

Don’t they have fine & polish modes
for blades that just need touched up? My understanding is that the rough or course setting is only used to smooth out nicks in the blade.


I’m sure there’s a learning curve with
them. Like I said, I tried it once and wasn’t impressed. As I recall, it seemed silly to me at the time to plug in and store a machine that didn’t allow any subtle control that I enjoy honing freehand and really didn’t save any time, either. There must be something to them, though, as they’ve gotten good reviews in cooking mags that I’ve seen.

That’s because most “cooks”…
…or “people who cook” don’t have a clue about sharpening knives or in many cases, even what a sharp knife looks like. Similarly, most people who own wood chisels, planes and such wouldn’t know a sharp one if it bit them in the butt. Unless one has actually used a truly sharp knife or tool, it’s hard to appreciate the difference and it seems many people still don’t get it even after they’ve experienced the real deal.



That said, I’m MUCH more finicky about my woodworking tools than I am about my kitchen knives. I would never use a sharpening steel on a plane blade or a drawknife, but it’s good enough for use in the kitchen.



As for paddle “cutlery”, I don’t carry a knife on my PFD, as I find a rescue hook does everything that I’m likely to need and it’s FAR safer to carry than a sheath knife. If I was paddling whitewater or rivers where snags were a potential problem, I might carry a knife, but for sea kayaking, you’re far more likely to be injured by a knife than to actually need it for rescue purposes.



BTW, I do carry a Swiss Army knife in my day hatch for spreading peanut butter and other chores for which a rescue hooks is not well suited. :wink:

Re the Rescue Hook

is yours the Benchmade version? I carry the older style in my pfd also but find it so small, i fear of dropping it in the water. Do you have any type of lanyard attached to yours? I am not sure if it would hold seeing as mine at the end has a slight opening in the hole. I see some now have an indent for the thumb with jimping- this looks like a better design for better grasp.

For a sharp knife
I’ve used a variety of sharpeners. I use the Lansky, and it’s great, but it’s not likely you’ll have it with you when away from home. I have a “Redi-Edge” which is, bar none, the best and easiest to use portable sharpener I’ve found. http://www.rediedge.com/



For the best and cheapest edge, try the “Super Scary Sharp” method. http://home.comcast.net/~kvaughn65/scary.html It works best on tools such as plane irons, but with an edge guide can be used for knives also.



The thing I’ve found is that all methods work, you just have to put the time in to master them.

Lansky here, too.

Never did well with free-hand sharpening. Won't use anything with a motor. The Lansky will put a long-lasting edge on. I have the bench pedestal accessory and that helps a lot when doing several knives at once.

Rescue hooks...I like this one and have it fastened to my pfd. It sees a lot of use...

Currently evaluating this knife for river use...

http://www.crkt.com/Renner-Neckolas-Neck-Knife-Blunt-Tip-Blade-Orange-Handle-and-Sheath

I like it so far, but I'm doubting that I will like it more than the hook-style. Sharpening the hook will be much easier and using it seems safer. I'm not sure what I'll use to sharpen the serrated edge of the Renner knife.

I know there are tools for sharpening serrated edges, but haven't tried any yet since none of my serrated blades have gone dull. Probably, this is because they don't get daily use like my plain blades and Extrik-8-R do. I have to disagree with what someone said about the points of the serrations not being sharp though. I've managed to disprove that claim, with much blood and embarrassment.

Atlantic Salt knife with serrations, he cuts himself -even just practicing opening it 2 days ago!
I like the CRKT knife you have attached to the pfd with the finger holes (i think this design on any knife is a bonus as less droppable) - cannot find out the steel makeup though.

Steel spec
Can’t help you there. For some reason, CRKT doesn’t seem to list that for the EXTRIK-8-R, although their catalog has the steel spec for all their other blades. An oversight, maybe? I don’t think it’s a huge issue on this type of knife though, unless you’re in saltwater. I bet a phone call or email to CRKT would get the answer to that.
