2 Swedish Air Force survival knives
on: February 17, 2021, 07:43:17 PM
Recently acquired these two fixed blades made by Swedish manufacturer Pontus Holmberg.
According to this website the model was once used as a survival knife for the Swedish Air Force: http://www.gotavapen.se/gota/artiklar/knivar/aforce/1survival.htm



I'm in the process of giving each one a bit of TLC, and will post some pics later on.

Blade hand reground to it's original full convex blade shape on a Foss 7205 black/green silicon carbide stone used with oil, then refined on 400 grit and 1000 grit SiC wet & dry paper used with oil on glass, and the tiny burr stropped off on hard cardboard with 1.0 micron diamond paste.
The new apex measures between 20 and 22,5 degrees inclusive.
Very hard (guesstimate 64-65 HRC) and also very wear resistant steel.
Handle reassembled, now with all washers glued and pommel repolished, then treated to a few coats of warm Granger's wax.
Sheath waxed and hand restitched.

The second knife is a bit worse, also due to the handle's leather midsection which had rotted over time together with a pommel stuck in place.

There is something wonderful about stacked leather handles.  Yours looks to be headed in the right direction.

The new leather midsection after rough machine sanding with a cheap Parkside linisher (which i modified so it can do slack belt sanding):

Looking superb Kwakster.  :hatsoff:  I do love a bit of stacked leather, but I'm now thinking I don't currently own any.  :think:  Might have to do something about that at some point.
Be excellent to each other and always know where your towel is.

The blade has been hand reground on the Foss 7205 combination stone (burr is partly visible), and a few refining steps on wet & dry SiC paper will follow later.
Now regrinding the swedge with 300 and 600 grit diamond files.

How the blade looks after hand regrinding to full convex again on the green silicon carbide side of the Foss combination stone used with WD40 oil.
The new edge angle measures ~20 degrees inclusive.

Currently experimenting a bit with different grits of diamond paste on thin cardboard to see what gives both a nice blade finish as well as a good apex.

Already found that only removing the burr is not enough to get the sharpest of edges on this steel, i have to continue stropping a bit to also get the (presumed tungsten) carbides into the right shape.
I also have to tinker some more with the appearance of the blade finish (now it's a bit too shiny for my taste), but the current apex is reverse hairwhittling sharp (chest hair) @ ~20 degrees inclusive.
