Sahmurai by Stefan Sahm



The Sahmurai Switchblade is a tire repair tool for the tubeless bicycle enthusiast.

Functions include:

  • A set of tire levers to remove the tire from the rim
  • A fork and reamer tool. The reamer tool prepares the hole in the tire to accept the seal plug that is inserted with the fork tool. The plug seals holes that are too big for regular latex sealant to seal.
  • Chain handling tool – to get the chain off or back on the drivetrain without getting your hands dirty.
  • Storage for a spare set of chain links – to connect a chain without a chain-breaking tool. 
  • Quick link chain breaker – this handy combination of the 2 Switchblades can break the quick link of your chain. 
  • Bottle cap opener – to enjoy your favorite drink after your ride!

The tool was designed to offer more than a quick plug solution for tubeless tire repair and to replace separate tools in your tool bag/saddle bag to simplify bicycle maintenance and repair.


Simple-to-store & most importantly, safe way of carrying a tubeless plug system

The SahmuraiSword (named after creator Stefan ‘Sahmurai’ Sahm) is an easy-to-use, simple-to-store and, most importantly, safe way of carrying a tubeless plug system on your mountain bike.

  • Built into what are essentially bar-plugs, the system allows you store both the plug and reamer tool inside your handlebars.
  • The SahmuraiSword fits snug and locks fast inside the handlebars without any give or movement.
  • It doesn’t affect riding in any way and you won’t know that it’s there.

The Sahmurai SWORD has had a make over, but far from just cosmetic, the improvements were done to improve functionality and aesthetics but maintain our original concept.
