Yesterday i continued playing / testing / finetuning the knife somewhere in the Veluwe nature reserve.
About a week ago i thinned the blade just a bit more and the new apex now fits neatly in the 25 degrees slot of my Tormek WM200, and so far the knife seems to be able to handle that angle without any problem when chopping various kinds of mainly green wood.
No rippling and no catastrophic edge failures.
The only visible damage i could see afterwards when i got home was caused by the tiny sand particles which are omnipresent in and on practically all the wood in the reserve, and which cause those telltale minute dents in the apex.
Sometimes a bit more, sometimes a bit less, depending on how close the chopped wood was located near the sand dunes.
But after about 10-15 minutes of stropping on a piece of MDF coated with 1.0 micron diamond compound & checking with my loupe all damage was gone and the apex was hairwhittling sharp again.
I intend to find out how often i can get away with just stropping the edge in this manner before i need to sharpen it again, which i do on a used sheet of 400 grit wet & dry on top of a big piece of fiber reinforced & semi-hard rubber conveyor belt.
On the wet & dry paper i use WD40 spray, which makes the silicon carbide grit cut more effectively, it keeps the swarf floating in suspension better than water, and it prohibits flash rust on the carbon steel.
Iirc the handle received 5 coats of IKEA cutting board oil, and after a long period of drying 1 more coat of Granger's wax to seal the wood.
Due to the contouring the handle now offers 3 hand positions:
- Exactly in the middle for a neutral grip (for general cutting)
- Against the integral pommel for maximum chopping power (for thick branches & smaller trees)
- Up front held loosely with your pointing finger in the cut-out for tip speed / snap cuts (for brambles, twigs, and thinner branches)
So far i have absolutely nothing to complain about this more than 50 year old knife, and it has already proven itself as an excellent chopper made in very well hardened steel.
