Expert Verdict — Reviewed by the SuperArbor Pro Desk

Cartridge-feed hook knives are popular for underlayment and felt work because you trade cartridges instead of fumbling with loose blades. Keep it holstered between cuts since the blade is non-retractable, and buy a spare 20-blade cartridge with the knife so you never stall mid-roll.

The blade is always exposed on this non-retractable knife; store it in the included holster, wear gloves when changing cartridges, and keep it away from your body when cutting.


Order the AJC Non-Retractable Janser Knife Green with 20-blade cartridge and holster for fast, controlled seam cutting.
