Razor blade carton cutter cat scratching board box

Making a scratching post for your cat has never been so easy! 

My cardboard strip cutter was designed with ease of cutting in mind. 

After many tests with different cutters that jammed or required a lot of effort, I created the perfect solution - using a razor blade. 

Thanks to this, each cut is smooth, precise and trouble-free, and the cutter itself works without any jams.

the knife housing is printed vertically with supports that are easily removed

to make the knife you will need: 

-half a razor blade (just cut it in half) 

-self-locking nut 

-m3 8mm screw

the razor blade is inserted and screwed onto the screw

the cutting itself is problem-free, without jamming and, most importantly, you don't need to use much force
