My Case Mini Copperlock is turning blue!

Actually just one blue spot has appeared on the bolster of my Case Mini Copperlock. This is not an EDC knife. I generally carried it once a week. I carried it in a small velvet lined buckskin sheath in my pocket. When in the sheath, the knife would be exposed to a narrow strip of buckskin at the seam. Could this be the cause of the blue spot? Or could anyone suggest what else the cause might be? I have some Simichrome polish. Would this be a possible way to remove the blue spot? I don't want to further damage the knife.

Any help would be appreciated.

Was the sheath glued or just stitched. The chemicals used in the tanning process could cause discoloration, but that looks more like a stain from exposure to some other kind.

It looks just stitched to me.

A stain from the dye in the velvet? Simichrome should take the best part of it out. you may have test it on a small spot and repeat it a couple of times.

Charles,

Might be oils in the leather, but any of the metal polishes should work - Simichrome, Metal Glo, Flitz, etc. Not sure why just one spot would be affected, except if the end where the spot is, is the end that went in the sheath/pouch first and maybe was a little tighter on the bolster, being at the far end of the pouch.

Maybe some Renaissance Wax will cure the problem.

Applied some Simichrome to the bolster and buffed it. The spot is now gone. Also noticed a similar spot starting on the bolster on the other end. The Simichrome removed it too.

should come off with some tender loving care with Chrome polish .....finger print oils can do that too!.....

Here's a tip that won't work for a Mini Copperlock, unless you can palm a basketball, but might for a smaller knife like a Peanut or Butterbean. Cut one of the fingers from an old pair of split-leather "cowboy"/ranch gloves - the ones with the draw string on the wrist. Nice leather pouch, and usually one finger will wear out before the others so when you change to a new pair, save the fingers of the old pair for knife pouches. Of course, by the time you retire the split-leather gloves you probably have more than just tanning oil in the leather. However, it has worked for me.
