They work even better if you sharpen them with a diamond stone...

I’ve sharpened ever masonry bit I’ve ever used. They cut better that way if you have access to a grinding wheel that will cut carbide. I move the cutting edge closer to the front edge of the carbide and then add a tiny bit of relief on the backside.

Hi guys, new to knife making and first post. first off let me say im loving the hobby and im currently half way through my first knife.
ive anealed a file, and so far so good, ive got to the point where i need to drill the pin holes in my handle and scales, yet the steel is still to hard
to drill with a hand drill and standard drill bits, and im a little weary of taking a tourch to the handle incase i ruin the blade hardening.
does anyone have any advice on how to drill a couple holes without ruining the knife blade hardeneing

Thanks in advance guys

I use TCT locksmith drill bits for getting through tempered steel, pick them up off ebay for £3 each, usually get about 15 holes through 2+ mm steel per bit. go at a low speed and dip the tip in water every 6-7 seconds to give the bit more life. You will ruin the tip if you try to drill at high speed for 30+ seconds without a break to cool it off.
