سكين عملة رين-داو

Carried this for two weeks now and the flat coin shape disappears into a jeans watch pocket without any bulge. The blade deploys fast enough that I actually use it instead of leaving it at home.

The blade locks in securely and the coin profile sits flat in my wallet without bulging, so it's easy to forget it's there until I need it. I've used it for opening boxes all week and the edge has held up nicely.

The coin form factor is what sold me — it slips right into that tiny fifth pocket on my jeans where a normal multitool never fits. Blade deployment takes a bit of finesse, but once you get the hang of it, it's surprisingly practical for daily opening tasks.
