I cant understate how great this is. $3 for a sizable pack of blades. these will last youthrough nearly the whole model kit- if not longer. I've used this to cut upholstery foam before - material that dulls out blades very quickly. I've used it to cut fabrics as well. It's incredible durable.

ADDENDUM: There has been a manufacturer change that presents the blades in a glossy case with removable top, as opposed to the semi-matte case with a flip top. Unfortunately I don’t feel that these newer blades are as sharp. These blades outperform XACTO and Excel brand #11 blades when cleaning up plastic runner gates in terms of precision and smoothness of the cut. I do find that I have to replace them more often, which may be because they are thinner. It’s a worthy trade off, in my opinion. Sliding the full length of the blade across the part will result in a far cleaner cut than simply pushing it through. I really can’t recommend these enough!

They are nice basic blades that get the job done they do feel a lot sharper than regular blades but that could just be me.
