Blade & swedge colored with a blue magic marker before refining step with 1000 grit wet & dry SiC paper, used with oil on glass.

After the refining step:

New JB-Weld "washer" sanded flush, and the blade hand reground to it's original full convex shape on the green silicon carbide side of the Foss 7205 bench stone used with oil.

The first leather washer had rotted and had to be removed.

Then the gap was sanded, cleaned, and filled with some JB-Weld.

Wet ground a new point & a rough new swedge on the side of my Tormek SB-250 Blackstone (black silicon carbide):

This traditional Argentinian Ju-Ca brand fixed blade belongs to a friend of a friend, and as you can see the point was broken off and the handle was also in need of a bit of TLC.

Pictured are two Norwegian Foss 7205 combination black/green SiC sharpening stones; the one used with WD40 oil for regrinding the two Pontus Holmberg knives, and an unused new old stock one i intend to use with water.

Sometimes i remodel worn out or discarded meat carving knives into very narrow shank-like knives, which i then give away to certain Chefs & butchers.

This old Swibo i did a few years back, and it has quickly become the favorite bird & trout knife of a local Chef.

The rigid blade is hand convex ground up to 400 grit wet & dry SiC, it has an edge angle somewhere between 25 and 30 degrees inclusive, and the back of the blade is also convexed to a degree (which thins the blade a bit more & allows for better twisting & turning)

The hard rubber-like handle has no real guard, only a few shallow finger grooves, which provide for quite a lot of grip.

Very useful knife according to it's owner.
