Made a knife
what's the original piece?
>>1291669Are you fucking retarded? Holy shit.
>>1291669Plane iron.
>>1291656Do you slay gaijins with that, noble senshi?
>>1291671yes
>>1291669impromptly made spokeshave iron
>>1291688I am Russian. We do not kill anyone))
>>1291671>knives can only be made with a forge>stock removal isn't a real knife
>>1291651Get a life.Bin that knife.
>>1291811>set one of these up>ebay all the free knives>make tons of money
why would you ruin a plane iron for this
>>1291929>set it up in the US >come back next week>completely broken open and robbed
>>1291656Good job anon , it's not the best looking or the most functional blade in the world but it's a good start. Keep making. Also only 3-4 cm of that blade are hardened by default . Did you rehardened it or you left it as it is?
>>1291724no its a plane iron
circular saw blades work well for these type of knivesyou will need tungsten carbide to drill it.
>>1292592>you will need tungsten carbide to drill itI think it would make sense to anneal the thing before working it, otherwise you'll wear your sanding belts much more. It's not like hardening it and tempering is a particularly difficult process if you already have the materials to be knife making in the first place.
>>1291669Keyhole. Tiny knife as OP cock.
bought an expensive knife it is still sharp AFmy diy knives are like butter compared to it
>>129259215N20 usually need to be annealed, heat it up to 800C and then stick it in sand or vermiculite until its room temp. I've noticed it will also work harden slightly as well so keep your drill bits cool, same as drilling stainless.
>>1292758lmao
>>1292663>>1292767too much work , why unhardend just to rehardend when the metal is prehardend to the best hardness
>>1293178I imagine a knife would ideally be hardened and tempered differently than a saw blade, but to each his own I guess.
>>1293178Because you don't know what the saw blade was hardened and tempered to in the first place. Each manufacturer probably has their own treatments for various steels and even the same steels so if you're trying to replicate a consistent result, you don't really learn anything from your own efforts.The biggie though is, you place the metal under stress, while its hardened + tempered by grinding on it, the metal will form fractures and differential heats over various efforts of beating on it with grinders, sanders, etc that will knock some of that hardness out, leaving you with softer and harder sections.15N20 is a really nice steel, it gets insanely fucking sharp and its damn tough, not so great corrosion resistance. However, you do need to anneal it before working, at least two normalisation cycles at 750-800C to air cooled. Then quench it in warm oil or it'll typically warp like crazy.I tend to quench for 10 seconds, then air-harden it between two slabs of aluminium in a vice to knock out any warps, bends and wiggles
>>1291811UK must be a real shithole for these things to even exist.
Finished. I'll think up a name and put it on the ebay
The hardness of the metal is 54-58 on the Rockwell scale.
