Trouble sharpening CRK Sebenza S30V Sharpmaker
- Thread starter 62strat
- Start date
Are you sharpening on the 30- or 40-degree setting?
Sebenza’s have a mild convex edge, and the Sharpmaker produces a flat V edge – at either 30 or 40 degrees -- or a 40-degree flat V edge with a 30-degree back bevel. The Sebenza’s convex edge approximates the latter double bevel that you can get on the Sharpmaker.
If you’re using just the 30-degree stone setting, you’re probably not reaching the apex with the stone. You might want to try just the 40-degree stone setting to see if that helps. You can also paint the edge with a Sharpie to see where the stone is making contact on the edge.
You can maintain the convex edge with sandpaper and a soft backing, but you’re not likely to produce as nice a convex edge as the Sebbie came with, and because you have a Sharpmaker you may as well use it. If the stone at 40 degrees doesn’t reach the apex, you have to just keep at it. The medium stone on the Sharpmaker is not efficient at reprofiling. You could get a set of diamond stones to make the process faster.

Two things will greatly impact how easily the SM can sharpen the S30V Sebenza: First, if it's very dull, with a long time since new or last fully-sharpened, and (second) the S30V will make that task much more difficult if it is very dull. If it is, diamond is the best way to get a workable bevel on it again. Once that's in place, the medium rods can add some nice bite. That's where I've chosen to leave off, when touching up two Sebenzas I have. I don't have the diamond sleeves for the SM, but have used a Fine/EF DMT 'credit card' to do the work that's been a little more difficult for the SM's ceramic rods to do alone. The Sebenza does have a (very) subtle convex from the factory, but it's nothing that'll get in the way of the Sharpmaker or any other V-bevel sharpening method. At the time I bought my Sebenzas, I'm pretty sure Chris Reeve was even recommending the Sharpmaker as an efficient tool to maintain the edges on them (again, so long as it doesn't fall too far behind in upkeep).

On both of my CRK folders I had to reprofile the edge to <40* before it would work on the sharp maker. I would bet that if you put sharpie on the edge bevel you would see that the stones aren't removing the marker at the apex of the edge. If you get the edge angle <40*, the sharpmaker works great for touchups but it's a pretty miserable way to remove any amount of steel.
