I think this is my second post here. Last week I got a very rusted Canadian WWII Era Clasp Knife. My Girlfriend bought it for me as an early Birthday gift. I knew what condition it was in before I told her I wanted it. It has no markings except for "M. S. Ltd. XX" on the tang of the main blade and a faint service number stamped on one side of the grips. There is no date, no "C Broad Arrow" or anything like that. The ony way I know it is Canadian is seeing other Canadian WWII era Clasp knives. The major problem so far is one of the springs broke. I have seen another thread in this section with someone else having the same problem. I had taken the knife apart and cleaned it up, fairly certain I can put it back together. However, I'm not so sure about making a replacement spring (would like to replace both whilst it is apart already), I'm living in an apartment in Toledo, Ohio, I would not want to try heating steel in this enviroment...LOL.
Has anyone here ever had somebody make replacement springs?, and if so was it expensive to have somebody do the work?

If this works, here is a photo of the knife when I got it.
