I wanted to replace some really old rusted and fragile blades from an old knife set that was my late father's. I'm so glad I found this handy little set, as it has the exact blades I needed. Now I have his old craft knife set back in clean and usable working order. Blades are of good quality, and should last for some time. It may not seem like much, but thank you HobbyLinc for having this available, and at a good price too.
