I purchased a leather sheath from SOG with the plan on using it for my Tomcat folder. But, I was advised by their customer service people to use the nylon sheath instead. They explained that the chemicals used in tanning their leather sheaths would attack the steal after awhile. The problem is I really like the looks of the leather sheath with their logo and it fits the knife so well. Is their something I can soak the sheath in or apply some sort of coating to it so that the tanning acids will not harm the knife?
