"I like these knife blades and i use them with a decent Stanley knife. They are long lasting but the only problem is that the tip of the blade can chip a tiny little bit, which does not really matter unless you are cutting carpet or something. that is why i have put 4 on performance. otherwise, a fantastic product, long lasting as well"
"i was a bit skeptical when i saw these but i am still on my first blade after several weeks which can't be bad. the do stay sharp longer but then they do cost more. not sure they could be classed as value for money."
