CNC-machined from Grade 5 titanium or hardened stainless steel, it packs a bottle opener, bit driver, screwdrivers and mini wrenches into a tool smaller than a house key — and it carries no blade, so it flies with you.

Is it TSA-safe?
Yes — the S Keychain has no blade, so by design there is nothing sharp to confiscate. The officer always has final say, but it carries nothing prohibited.
Titanium or steel — which should I pick?
Titanium is lighter and won’t corrode; hardened stainless steel is more affordable and just as tough for keyring duty.
Does it fit a standard keyring?
Yes — the hole takes any standard split ring, carabiner or lanyard.
What bits does the driver take?
Standard hex bits — the same kind that fit most pocket bit sets.
