Mouse would escape the tape and stick its head through the ring. Then you have an invisible mouse to rule them all to deal with. The whole of Middle Earth would be absolutely overrun with mice

Technically it would be low cal compared to a normally sized calzone just because of being significantly smaller.

LOL I totally identify with this. I don’t remember upvoting, but it looks like I already did. Just un-upvoted and re-upvoted for good measure.

It’s actually surprisingly easy! I’ve done it a few times for my other knives because my wife is morally opposed to having a knife block on the counter. So our knives go in the drawer each with a custom sheath to protect the blade.

All you need is two pieces of wood, each with at least one good flat face. You trace the knife on both sides of one of the pieces of wood. One tracing will be the inside of the sheath (the flat face if you’re not using s4s), the other tracing will be on the outside which you’ll use as a reference to shape the sheath. You then chisel or route where the knife will go, place the knife in it to make sure it fits properly. Glue the flattest face of the other board to the side you just routed. Once the glue is cured, use a belt sander to give the sheath the general shape you want, then orbital or hand sand to get it nice and smooth. Apply finish of choice, then you’re good to go.
