Someone posted on Youtube to ask me to talk about the Stanley knife I am using in my videos on making the European workbench used by joiners, carpenters and furniture makers through the centuries. I guarantee one thing, at least I think, they would have loved to own the Stanley knife I have been using for years. It has become the only knife I use for 99.99% of my work and every students that discovers it demands to know where they can get it. I walk in my local Richard Williams in Deganwy and buy them there, but I have bought them in bulk.
Both knives have a comfortable and attractive epoxy coated die-cast metal body folding pocket knife. They close with a simple spring mechanism that enables the blade to be locked securely in the extended position or stored safely within the body. The knife comes with 2 x 5901 (Stanley 0-10-958). Spare blades are contained in the handle as per other Stanley utility knives.
As I said, I resharpen my blade over and over a thousand times or more in its lifetime, but replacement blades are only £3.50 for three. On the other hand, I discovered that Stanley makes a disposable knife that actually has the same 5901 (for the Stanley 0-10-958) blade in the plastic holder and these fit their Stanley 0-10-958. You can buy these in packs of three for under £1.50.
As you can see, I advocate diamond plates for sharpening and I have 3×8 plates, but smaller ones will do the same for knives. This is simply a matter of eyeballing the same angles on a fine plate and rubbing back and forth until the new cutting edge emerges. Any burr quickly falls of as soon as you use it.
