You don't have to have a hobby to appreciate the sheer genius of the Powerbuilt retractable blade hobby knife.
Instead of the usual razor sharp fixed blade waiting in a drawer or tool box to take a blood sample from your finger, this hobby knife offers an elegant solution: just twist the knife body to expose the blade for cutting, then twist it again to retract the blade closed between uses and for storage.
Nothing could be quicker, easier or safer. It comes complete with 3 blades and accepts standard hobby knife replacement blades.
