Sharpening small blades can be a challenge, and there have been several discussions here about how they fare with various sharpening systems. I mainly own and use traditional folders and so have plenty of small thin blades to sharpen (and I like my knives sharp). I had good luck with my original model Work Sharp on these small blades, and I've had even better luck with the Ken Onion Edition.

There are several improvements in the KO version, and the different reviews here on the forum discuss them. What I've come to believe is that the most significant one of all is the variable speed motor, especially when it comes to small blades. The beauty---and the danger---of a belt grinder is how quickly it can remove metal. With small blades, of course, there isn't much blade real estate to begin with, so you really want to avoid removing any more metal than you have to. Moreover, any mistakes are exaggerated by the small blade surface you're working with. With the KO Edition, it's great to be able to crank the speed down to somewhere in the low-to-medium range and thereby have a lot more control over what's happening to that small blade. Frankly, the variable speed is great for all size blades, but with the small ones it's even more important.

I'm putting up some quick pics here to show how I have used the Work Sharp to set the bevels on my traditional folders. Some of these were done with the original model and some with the KO. (If you notice a slight "recurve" in the heel portion of the blade, the blade was probably done with the original model---just a split second of "lingering" in the start position with the motor at full speed can cause this right quick.) I wanted to show small, medium, and large traditionals, with a variety of blade shapes.

I should note that I sharpened these knives freehand style on the WS. I do sometimes use the guide, mainly on larger kitchen knives, but it justs gets in the way with small blades.

I usually sharpen at around 13-14 degrees (26-28 inclusive) because I use my knives lightly and I like the cutting performance this provides. In addition, I touch up the knives on my Sharpmaker at 15 degrees (usually the UF rods), and so the less-than-15-degree bevel makes that possible. (My final touch up is usually a denim strop with either Bark River green compound or Mother's Mag polish). I imagine that the wide bevels you see in many of these pics may not seem "traditional" to some, but of course the WS will let you sharpen at a more obtuse angle if that's your preference.

Finally, the point of this thread is not to convince anyone that I'm an accomplished sharpener, because I'm not. I spend a fair amount of time on this subforum and I see what the really skilled guys can accomplish, and I am in awe of their abilities. In contrast, on a good day I might qualify for the lower end of intermediate---that's about it. But that's also my point: the Work Sharp, especially the KO Edition, has made it possible for a guy with limited skills to have and enjoy very sharp knives (the knives in this thread will all easily slice and/or push cut phone book paper).

So, on with the traditionals.

Let's start with the smallest: a couple of Schrade 12OTs with nice clip blades:

Next are a Case Swayback Gent with a wharncliffe blade and a GEC #25 with a drop point:

Next is a trio from Case: Canoe, Humpback Stockman, and Medium Jack, showing their pen blades:

A Case Mini Trapper and a Case Medium Stockman, with two different size spey blades:

The same Medium Stockman showing its sheepsfoot. I had a small problem with this blade---the WS left it with a slightly "wavy" edge. I ground it straight on a Norton India stone and then finished it on the WS.

A pair of GEC #15 Boys Knives, one with a clip and the other with a slim spear:

A couple of fatter spears, on a Case Canoe and a GEC #55 Houndstooth:

A Case Sowbelly with an upturned clip and a Schrade 5OT with a drop point:

Three big clips, on a Case Copperlock and two versions of the Case full size Trapper:

Finally, a couple of large speys, from the same Case Trappers:

Thanks for reading and looking.

I agree. I've also had good luck with the Work Sharp. It took some practice for me to figure out how to not round off the tips, but having the variable speed version is (for me) key. It also is useful as a tiny belt sander if you want to modify blade shapes:

You say you sharpen at 13-14 degrees, freehanding on the Work Sharp. How do you know what angle you are at? I also freehand, only using the edge trailing side. I hold the knife straight- pretty much the same as on the Sharpmaker, letting the angle of the belt set the edge. I guess it's somewhere under 20 degrees because when I finish up on the rods at 20 degrees, it seems to clean up any slight burr and put a crazy sharp edge on.

My memory is that if you hold the blade straight on the WS you'll be at about 17.5 degrees. So, finishing up at 20 degrees on the SM would work well.

I'm just eyeballing to get my approach at a bit less than 15 degrees. But it seems to work because I get the same nice deburring and slight microbevel when I then use the SM at 15 degrees.

I also think the amount of pressure and resultant belt deflection will impact the amount of "convex" that is attained. Simply put, the more you push the more "rounded" the profile, thus the more obtuse the actual apex even though the shoulders will be nicely rounded.
 
One more: GEC #73 Scout in coco. Just put an edge on this one today. The thin bladed #73s are great slicers. (This one came to me with its mirror finish all scratched up, so it was given a quick "satinize" treatment).

Have you taken any video of how you are doing this exactly? I guess my main question would be are you just letting the belt turn continuously and then putting the blade on the belt and pulling it across or are you putting the blade in place then pulling the trigger and pulling the blade across the belt? Your only using the trailing edge right?
 
jkulysses,

I haven't done any videos. Brian G. has done one here on his 2-hand technique: http://www.bladeforums.com/forums/s...rp-Ken-Onion-Impressions-and-Discussion/page3 and TWANGnBANG has a video here: http://www.bladeforums.com/forums/showthread.php/1125418-Work-Sharp-Ken-Onion-Edition-Video-Review

I place the blade gently on the belt and position it first and then start the belt. As the manual says, and as I referenced in my OP, you need to begin drawing the blade down the belt simultaneously with turning on the power. Otherwise you are going to oversharpen the heel portion of the knife. The coarser the belt grit and the higher the speed you've set, the more critical this becomes.

I freehand and typically only use the angle guide and the edge guide with long kitchen knives. I think a lot of the guys who are good with the WS use edge trailing only, but I'm still experimenting with this. For a while I was doing edge trailing only, but recently I've been doing it a lot with edge trailing on the right and edge leading on the left and seem to be getting similar or even better results, plus it's faster. I will usually do a finishing pass or two as edge trailing, though.
