Thank you for the positive feedback
I have started to work on a guard, from some 8mm stainless scraps I found at the sailboat harbor where my boat is docked.
They have been doing a bunch of renovating, and learned by now it's not gonna be easy to forge.
My best guess is it's 316L or something in that range, as to my knowlage it's the most common used at sea around here.
Filing sure takes a bit of time, I haven't been able to find all the files I want/need.
Trying to my best, to get a good result with what I got.
Still got a bit of work left, on getting all the angles right.
The fit on the sides, I think turned out all right for my first try.
Might be easier to file and fit, picking something softer and thinner then 8mm Stainless.
But I figure I got that, it's free and again im learning. In this case maybe more like, refreshing old memorys from shop class.
There are tiny small gabs, but there is not a lot of light shining thru.
I can't wiggle it in any directing, and holds the blade in place so I think it will be all right.
