Seam Rippers
These are double ended tools that allow someone to take a sewed seam apart.
The sharp end of the tool can be
reversed and is stored in the barrel, so you don't get poked or cut with it.
The top 3 are turned with wood blanks, and the bottom one is acrylic.
Here's a close-up of the ripper part, it comes with a large and a small one on each tool.
