model from 1979 I believe, as it's marked "C".
I use Marbles leather sheaths for under 5" blades if the originals are damaged or missing.
They are under $10 delivered if you look around. They are not bad at all after a little saddle soap or polish.
Producer, I have seen on AAPK bad reports on the modern Marbles Moose & Goose sheaths. Possible
causing blade staining.

Stockman, thanks for posting this.
I've used 5 of these in the last few years[no problems] but the last one ,purchased about 4-6 weeks ago, I had a problem with a Westcut K-5 after leaving it in the sheath overnight.
It was like a staining to the blade as you have said. I thought it was the polish I had used on it even though this had never happened before.
I wasn't aware of this until now but it makes sense.
Obviously I retract recommending these sheaths.
I did mange to clean up the K-5 and the sheath is usable now but I [instinctively?] had moved my least liked blade into it.
I thought it was something in the saddlesoap/polish I had.

Thanks again
Harold
