RAY Studio OnePass Wide Blade Hobby Knife
RAY Studio OnePass Wide Blade Hobby Knife - Black Knife is backordered and will ship as soon as it is back in stock.
The RAY Studio OnePass is an all-metal hobby knife built around wide, stiff blades and a dispenser that lets you change them without ever touching the edge.
Touch-free blade changes
The OnePass dispenser holds 15 wide blades. Push the chuck in, take one fresh blade, lock it, and drop the old one back in the case. Your fingers never go near the cutting edge, and you always know where the spent blades are.
Wide blades for cleaner cuts
A wide blade flexes less than a standard #11, so it shaves sprue nubs flush and scrapes seam lines evenly instead of digging in. It is just as useful for chamfering edges, removing 3D print supports, trimming decals and cutting paper or plastic card.
Solid metal handle
- Full metal body with a knurled grip that does not slip in the fingers
- Electroplated brass chuck that also accepts standard hobby blades
- Includes a scribing needle for panel lines
- Available in black or blue
