We've often been asked for replacement blades for stencil knives so we are now stocking standard X-Acto and Swann-Morton blades alongside our Goldmann blades. We still prefer our trusty Goldmann knife for weeding and cutting with. It has a 4" long resharpenable blade which has far more strength than a scalpal blade and also lasts a lot longer. Should you eventually run out of blade on the knife, replacement 4" inserts are also available, over time these knifes pay for themselves many times over.
