Gadget for sharpening chisel ground blade

[premio53]

Hi everyone. I will be getting a knife with a chisel ground blade which I have never had before. I usually sharpen my knives with a simple two step sharpener similar to this.

Are there any gadgets available that will allow me to sharpen it other than free hand on a whet stone? Will a chisel ground blade be ruined if sharpened on both sides? It seems that eventually sharpening on both sides would result in a regular hollow or flat grind.

Depending on the particular knife, some options may be much simpler than others. Some chisel grinds are overly complicated with multiple bevels, recurves, hard corners, serrations, etc., and others are very simple with a single linear edge ground on one side. Might post a pic of what you're considering buying. Then you'd likely get some better feedback as to what will be the best sharpening solution.

The quickest answer... what you're using now isn't a very good sharpener, so you may want to spend some time reading thru this forum, and choosing a sharpener that will work better for ALL your blades. The sharpener you referenced doesn't do a very good job... especially over time... it can do more harm than good.

If you don't want to learn freehand... then look for information on guided sharpeners: Lansksy, KME, Wicked Edge, Edge Pro, DMT, etc.

Actually I plan on getting a Leatherman Squirt PS4 which has a chisel grind blade for carrying in my pocket. I probably need a system that will sharpen on one side at a time. Are there any very simple gadgets that will work? Thanks.

That should be relatively simple; about the simplest in fact, in terms of the grind of the blade. I have a Leatherman Micra with the same chisel grind. If you're really wanting something to help with the angle, a simple V-crock sharpener like the Sharpmaker or Lansky turnbox could do. Sharpen the bevelled side as per any normal knife, with the bevel flush to the rod on one side, or with the spine oriented vertically, which would likely apply a small microbevel. The unground back of the blade could then be set flush, or very nearly flush, to the sharpening rod on the other side. The unground back side of the blade could also just be laid flat to a hone/stone, or a hard strop used with edge-trailing strokes. For the 'hard strop', I've liked wood (basswood, maple or any other smooth, tight-grained wood) with white rouge or other aluminum oxide compound applied (Fiitz, Simichrome, Mother's Mag polish, etc), as they handle the 420HC burrs very well.

On that knife, the blade might be too small (narrow) to take advantage of a clamped guided setup (Lansky guided system, Gatco, DMT Aligner, etc). For a similarly-ground larger blade, one of those could be used to sharpen the bevelled side. Some generations of Lansky clamps have a small notch milled into the front of the clamp's jaws, for smaller blades. On those ones, they might handle a blade of that small size.

Thanks a lot. I carry a knife at work and have used the simple sharpeners for years with great results. I know the carbide rods can take too much metal off so I only use the ceramic rods and can't complain about the sharpness.
