I recently bought a chef's knife at a garage sale and I think it's a fairly high quality knife. The blade is 10" long and I've found that it's too long. I use my 8" chef's knife a lot and would like a second 8". So my question is can I cut down the 10" a couple of inches? I have very little experience working with metal. I have several tools that I would use if I take on this project: a bench grinder, a Dremel tool and a Work Sharp sharpener - one of those mini belt sander sharpeners. My thought is to cut the knife to shape using my Dremel with a cutoff disk, basic shaping with the bench grinder and then final shaping and sharpening with the Work Sharp. I'm not opposed to taking it to a professional knife smith, but thought I'd take a crack at it first. I'd sure appreciate your advice or any tips.

Hi. I am currently doing an apprenticeship in mechanical fitting. Everything has been going great and i am on my last project where part of it includes drilling 3, 5 and 10mm size holes in 10mm thick steel with a hand drill. It has to be square and the sizes of the holes to a tolerance of 0.15mm. Now i have no problem with the 3mm and 5mm holes but the 10mm hole is giving me all my days of trouble. Mostly the size comes out between 10.15mm -10.25mm. The 5mm holes come out nicely and consistently at 5.05mm-5.10mm same with 3mm. Any tips on getting the size of the 10mm hole way down? I have tried many things but still no cigar😂 They are very strict and when i test i cant afford to fail because the 10mm hole is just slightly too big.
