Gerber’s Prybrid X is a pocket tool sized to accept disposable #11 disposable X-acto hobby blades. The blade is retractable for carry and the Prybrid X also incorporates pry bar and functionality as well as a bottle opener. Offered in Flat Sage Green and Urban Blue.
I think clip would have been more handier than paracord wrap.
I can see a keychain getting put through the 550
Two points.
1) I don’t see space on the tool for spare blades.
2) X-ACTO blades are darn fragile. Their intended use isn’t for something that marries up with what the pry bar at the other end would be used for.
Gerber’s Prybrid Utility appears (I haven’t used) to offer a more useful blade.
