Hey Sig210...
Thank-you for a quick response... coincidentally I had a beautifully written personal response from Anne Reeve herself which is just full of great history of the MKIII blade...
Stoked its made of the D2 steel and in 38years of some gnarly 80's Suzuki SJ410 roof of Africa adventures and my Jimny gen 3 off-peste SaniPass bushwhacking, between us, we haven't managed to completely destroy its edge geometry. I know my old man would've picked it up visiting his brother in Sandton JNB and probably lorded it over him... Ironically I was living in Durban Essenwood a stones throw from the Reeve's original workshop when we lost my old man..... somehow just feels a good fit with the blades provenance... what a chapter to add.
From Anne Reeve.
Hello Tom -
Thanks so much for your email regarding the Mk III - it is wonderful to see such a venerable old friend! While I get questions about older One Piece Knives fairly frequently, rarely does a Mk III pop up.
A little history of your knife: Chris developed what became known as the One Piece Range in the early 1980's. He came up with the concept of machining an entire knife out of a single bar of steel, and worked on two iterations before deciding he liked what he designed into the Mk III (i.e. the third iteration). Our records are very incomplete but I do have a note saying he made a total of 89 Mk IIIs. I would say your knife was made in late 1983, since he introduced the Mk IV in 1984. The only difference between the III and IV is that the IV has a double cross guard. Even though it has been well used, your knife is not too far off the original blade geometry. The blades on the Mk III and Mk IV are essentially the same and you'll be able to find pictures of a Mk IV in Google Images. We continued making models of various lengths and shapes until we retired the range in 2009
This knife is made of D2 tool steel made by Bohler Steel in Germany, that was heat treated to 55-59 RC. The butt cap is made of D65S aluminum and both are coated (it is not anodizing) with KG GunKote.
It is hard to know where or when your dad bought the knife - I can only say we did not have an official dealer in Nelspruit! Back then, we used to sell our very limited production through Sharp Edge Sharp Shooter in Sandton City and a gun store (I can't remember the name) in Durban.
I hope I have answered most of your questions and if I can give you any further information, please do not hesitate to contact me.
Best wishes
Anne Reeve
