Hi I have your hobby knife and rotary blade set. I'm looking for replacements blades (no.4), do you do them at all? I cant find replacement blades for the hobby knife anywhere and it seems a waste to buy a whole new kit everytime when all I use are those one blades (I'm a gilder and use to get rid of excess when working on glass so only a small horizontal edge blade will do.

Cheers
Kyrie
