cleaning an old metal clasp knife.

What is the best way to clean an old steel? army clasp knife which I recently bought at a Pop Up Shop in Kelso today?

Googling tells me to soak it in coca cola overnight, amongst many other methods, but I’m a bit apprehensive - have any of you any experience of doing something similar? I don't want it 'museum quality' just cleaner.

It is fortunately not rusty just a little mucky black gunge in places. Thanks in advance.

I would start with very hot soapy water and a soft brush. Then dry and soak in Gunk. Also a soft brush and WD 40 with a cloth to finish. I would not use Coco Cola.

john bunyan, thanks old pal, will do when I have bought some gunk.

You could just soak it in WD 40 overnight then use a toothbrush to get into crevices. at least with wd 40 you don't have to worry about having to wash it off.

I was going to follow JB's advice but as I had some WD40 handy I followed carver's advice - By Heck, what a transformation, it looks like new.

All I need now is to find out how to put an edge on the blade - I don't want it sharp enough to shave only to cut through string and the likes?

Emery cloth on a flat file will get the Edge back, then a smooth oilstone to fine it.

I've got a set of these diamond coated sharpening 'stones'. They're actually plastic boards with a metal diamond dust coated plate attached. I've had them for years. I think I bought mine in Lidl. I use them all the time for my Kitchen Knives, scissors, etc. and they are brilliant.

It will be made of an early version of Stainless Steel. Good for repelling rust, bad for keeping a sharp edge on the blade.

As an ex-Boy Scout, I think that I ought to point out that there is no need to buy a special sharpener, almost any stone will do the trick

I have an identical knife but the date is 1956. I always thought that it was faulty because the blade isn't fully recessed into the handle but I see that your knife is just the same. Good job that I haven't tried to fix it.

If you have used it be very careful as the tiniest bit of DNA can be found even after cleaning.
