    Great quality and will save me working with blades getting more & more blunt.

    Danny Lopez
    John Powell

    Perfect. Excellent quality.

    Brian Reynolds

    I have been wanting to buy a new snap-off 18mm utility knife for a number of years. I have two old ones where the blade had started to slip. I purchased a cheap version on Amazon, and returned it as it was even worse. I then came across the name of "Olfa", and the fact that they actually invented the idea of the snap-off blade. I purchased my first Olfa knife and I am delighted with it. I wish I had discovered them years ago. I am only a little older that the first Olfa snap-off knife. If I ever have to buy another snap-off knife in the future (maybe a 9mm version) it will certainly be from Olfa. I wish I found you earlier!
