Restoring older knives is one of my hobbies, and i think this one came out rather well.
No Tormek involved, all regrinding/sharpening was done by hand on a bench stone and refining on wet & dry paper.
The knife is a made in Sweden Pontus Holmberg first model survival knife for the Swedish Air Force, made between 1948 and 1952.
This is how the knife looked when i bought it:

And this is how the knife looks now.
Blade has been hand reground/reshaped to it's original full convex shape, and in the handle the rotted leather midsection was replaced with new leather.
Sheath was also hand restitched and waxed.
