When I purchased my Vic Ranger, I never expected to use the chisel. To me it was a useless blade. However, one should never say never. I volunteer at a museum and we had some metal tins, approximately 80-90 years old, some of which we could not get open. We tried the smallest screwdrivers that we could find to no avail. At that point I thought of my SAK and then thought of the chisel. It slipped right in the crack between the top and bottom of the tin and with a slight twist of the knife, the seal was broken. We were able to open the tins, remove the specimens with no damage. All I had to do was a quick run of the chisel over a stone and it was as good as new. Chalk one up for the versatility of the SAK.
...I gotta say, volunteering at a museum sounds kinda fun. I bet it gives you loads of fun opportunities to use your SAKs!
