Keeping the crooked knife sharp

The crooked blade is extremely helpful when carving concave shapes such as those needed for bowls and spoons. Unfortunately, this helpful shape can be tough to sharpen on traditional sharpening stones. The best solution is to make the sharpening gear fit the blade shape. Here's what I use, and how to make your own.

First, gather the items seen in this first photo. You'll need:
-scrap of leather
-polishing compund (I'm going with Flexcut Gold, but jewler's rouge or the like will work too)
-sandpaper of varying grits (here I'm using 220 and 600 wet/dry)
-three straight sticks about the size and shape of the inside curve of the knife blade
-stapler with staples

Cut the leather to wrap once around a stick, fuzzy suede side out, then staple it in place. I used a basic office stapler, but I suppose a staplegun would be even better. Apply some of the polishing compund to the leather. Do the same with the sandpaper on the other two sticks, only without any polishing compound. You now have two sharpening sticks and a strop for your crooked knife!

When using the sharpening sticks and strop, wipe them down the blade from spine to edge. Only go in this direction. Start with the coarsest stick first, then the next finest, and finally polish with the strop.

When you're done, the edge should be nicely polished and sharp enough to remove arm hairs. Careful now!


  1. Sharpening is a lot of bother, but the alternative is a nightmare.

  2. Thats a lot of help, thankyou.
