I recently posted some pictures of a grinding fixture that I made for sharpening tangential cutting tools . I needed to hand turn part of a new cross slide handle , for this I use a homemade graver as watchmakers gravers are a bit fragile for hacking chunks of bar stock . Just dawned on me that said graver can be sharpened on the same fixture , this would be a work of genius always assuming that I had done it on purpose . One more brain cell and I'd be dangerous .
