I have seen a lot of heavy use blades but the extend to which this billhook was used is among the hardest cutting I have ever seen a blade come through and still remain functional. It did take some work to get through the thick layer of rust on the edge and it revealed an edge which was simply manged beyond all expectations.
However a 36 grit belt quickly knocks the edge back into shape, and considering this is likely spring tempered, there is no concern about edge draw during grinding as would be an issue with low tempered high HRC edges and I know I will have to remove about 1/16" more metal to just get past the stress fractures from previous use anyway.
The handle as well was basically covered in grime and was sticky with what I hope was glue, that was also all removed and lighted covered and then buffed several times with linseed oil. The edge was then sharpened and could easily slice newsprint with 90% of the edge though was still ragged with small chips every inch or so left from the huge ones visible on camera.
It is however easily functional enough to start getting some use. Specifications :
-740 grams
-edge is 13.5 (5) dps
-16" over all, 10.5" blade
-4" wide
-balances 4.5" in front of the handle
That edge is the original grind, only 13.5 degrees per side, a typical Mora is 9-11 degrees per side, for a very heavy duty tool this was not keep at a very abrupt angle but kept at a very low profile to obtain very high cutting ability. This amount of weight, forward balance, and extremely low angle is an almost dangerous amount of cutting ability.
