Carpet fitting cutter Loop Pile Red Hessian Carpet Cutter

This "cutter" uses some strange obscure box blade(not utility or suicide) that neither i or any of my coworkers have ever seen or know where to readily purchase. So i was forced to use the blade it came with till it had no edge left and than throw this cutter away and purchased a real one from some where else

Utility knife will do the same job wasn't too impressed but didn't return it.

Does not fit standard carpet blades!!!! It’s a complete waste of time and money , returned immediately...
