good quality

Works really nice but I don't know how to change out the blades

Works good just can’t change the blade. No instructions in the package just new blades.

Changing blades

Just unscrew the knife a little and push up. That should push the part that holds the up and it’ll be able to change it. After that, just pale sure the little pin goes in the groove it was in while screwing it back.

Difficult / dangerous to replace blades

The knife itself seems fine for the price. It comes with a handle and a number of replacement blades.

The one major issues is that it is confusing and difficult to replace the blade. Removal can lead to slipping and cut yourself. Be very careful.

Good luck

No instructions for changing the blade and unlike any other similar tool.

How I changed the Blade

I used plyers to hold the metal part at the top. Twisted from the long orange body section. It comes in half. The slightly pull down on the finger portion and the collets will separate. Proper picture instructions are really needed in the back.

Don’t but this knife

You will cut your fingers off trying to figure out how to change the blade.
