Swivel scalpels 360° conduct rotation

The handle is articulated in the middle to be able to have a movable but controlled blade. The pumice and the middle finger are used to control the position of the blade. The index is used to control the pressure on the blade (and therefore the depth of cut). This type of tool is traditionally used for working leather.

The short blade is from a snap-off "18mm" cutter blade, they can be found in all DIY/fine arts stores. A.C.M. blades #11 #16 exist in many brands (swann morton, x-acto,...).

I also offer tungsten carbide blades, much more sharper but more brittle, for cutting thick paper, leather, and for relief print in wood or lino. The sharper the blade, the more precise it is, but the more brittle is the tip:
 - The "pointed" blade is to be reserved for cutting in the paper
 - The "truncated" blade is perfect for cutting into leather, works great for papers and board, and for relief print to use for precision work (lino, plywoods or woods)
 - The "straight" blade is the strongest, to be used in relief print (lino, plywoods or woods), and for thick leather
