Remix that adds a bottom side dedicated to bigger ampoules (now fits DIN 1 - 20 ml ampoules).
The original design worked well for DIN 1 - 10 ml ampoules but I could not reliably open 20 ml ones cleanly (such as the propofol ampoules widely used in hospitals). The profile has also been slightly slimmed for convenience. The hole for keyrings is retained.
Available in versions with or without embossed text indicating the side to use for different ampoule sizes
