Utility Knife

Would Recommend

The two pack with one large and one small is a good deal for the price. I have purchased these before and they work well. I decided to purchase another set so I would have one set outside and one set inside.

Safe Blades

Would Recommend

Ive purchased two of these blades for home use. I purchase a lot and I end up having so many boxes; I keep these blades to breakdown the boxes, and use them for lining my pet bird cage. These are perfect and safe to use.

The 18mm is hands down better of the two.

Would Recommend

Used these to cut indoor/outdoor carpet for a toolbox. The 18mm worked great, but the 9mm is only good for cutting tape, cardboard, etc.

Poor quality blade. Flexes too much. Go to dollar tree and get a better tool.
