DeWalt 9-1/4" Retractable Utility Knife Black/Yellow 1 pk

I can see where the other reviewers are coming from about poor instructions for initial setup. There are some small images on the front for inserting new blades and text on the back about how to remove the knife from the packaging but it still took some trial and error to figure it out. Used it to cut carpet and underlay. This is the first time I've purchased a premium utility knife and it was well worth the money. Comfortable, well constructed and holds an edge. All around great knife.

I'm a roofing contractor, I use these retractable knifes every day. this one I only use straight blades as not too much trouble to change out the blade. On the bottom of handle is a resesed button ( I use my hook blade knife to open and to grab button and pull towards front end on knife while pushing up,this opens at the top and now the compartment opens and holds about 6 blades. grab one and close. next you push retractor button on top to front of knife and on side is a little button you push in with strong pressure, the blade will then slip out the front and put in a new one. you do not need to run and get a screw driver. its all right there [This review was collected as part of a promotion.]
