Old Marble's Ideal
on: September 13, 2018, 06:41:58 PM
Recently i bought an old Marble's Ideal which had lost quite a bit of it's original blade shape due to it probably being used as a digging tool in the past.
It had no point to speak of nor any edge left, and next to some corrosion and grinding marks' it had quite a bit of those telltale deep scratches running lengthwise in the front half of the blade.
Since the steel is noticeably harder than my F.Dick basterd file nr.1 i tried something different this time to get the blade back into shape again; a Chinese made 120 grit diamond file from E-Bay costing a whopping 6 dollars including shipping.
This actually worked quite well and within a reasonable timeframe to restore the basic full convex blade shape the knife originally had, and of course without any chance of overheating the old carbon steel with it's quality heat treat.
Also recut the swedge with it.

Previously i disassembled the stack, numbered each washer, and reassembled it using glue between each washer, then hand sanded to shape:

Refined the blade surface with 240 grit, 400 grit, and finished with 800 grit wet & dry on a rubber backing using WD40 as a lubricant.
The apex measures just a hair below 30 degrees inclusive and is sticky sharp (can whittle a chest hair from tip to root)
Next step will be some test whittling into an old piece of cutting board (hard beechwood) to see how the new edge holds up.

Awesome.  :tu:
I had been looking at these recently to add one to the collection. They mostly seem to go for pretty good money especially if one of the earlier stamps.

I have the exact same knife that my Father used in the Scouts back in the 1930's a bit more used, battered and sharpened though, a real working knife.
