be careful with that artifact, I read it can open up in your pants and try to cut your balls off. Alot of shit was talked about that tool, I think i even saw pictures of some graphic injuries
That is something nice about the style keychain knife, because the blade is hard to open. I have the smallest of prybars on the keychain (titanium, same size as the width of a key and that long) that I can open the knife with. I think its good that its stiff. I have seen keychains do crazy shit when the angles are correct for the keys
As for the fish scaler,
"A novel usage for the fish-scaler is for Halloween pumpkin carving; the wide serrations are apparently ideal and because the tool is safe for younger carvers it might even be the best suited tool for the job ever! The shallow serrations can also be useful on soft materials, like styrofoam, that could clog up a sharper saw.
The forked tip can also be used as an impromptu cocktail fork, or key for paper towel dispensers or other insecure locks. The fish-scaler can also be used as a non-sharp prodding tool, if needed, as most other tools on a Swiss Army Knife are sharp. "
