Item specifics
Product Overview
These 9mm snap-off blades are purpose-built for precision cutting in demanding applications โ from vinyl wrap installation and window tinting to wallpaper trimming and packaging. Each blade is crafted from high-carbon SK5 stainless steel, delivering a superior balance of hardness, edge retention, and corrosion resistance that standard carbon steel blades simply cannot match.
The double-honed cutting edge is ground to an exact 59-degree angle, which optimizes slicing power while significantly reducing the risk of blade breakage during use. This precise geometry means cleaner cuts through vinyl, film, tape, shrink wrap, cardboard, and caulking with less effort and fewer blade changes. The stainless steel construction also makes these blades ideal for wet or humid environments where rust would quickly destroy ordinary blades.
With 13 pre-scored segments per blade, you get a fresh, razor-sharp tip every time you snap off the worn section โ maximizing the usable life of each blade. This 10-pack provides ample supply for professionals and serious DIYers alike, ensuring you always have a sharp edge ready for the next cut.

How to Use & Replace Blades
Ensure the blade is fully retracted. Slide the mechanism to open the handle and remove the old blade if one is present. Always work with the blade retracted when not cutting.
Hold a fresh 9mm snap-off blade by the flat sides (avoid touching the cutting edge). Slide it into the blade channel with the scored segments facing up and the sharp edge pointing forward.
Close the handle or tighten the locking mechanism until the blade is firmly seated. Extend the blade slightly and retract a few times to confirm smooth operation.
When the tip becomes dull, retract the blade fully. Use the snap-off notch on the handle or a pair of pliers to break off the worn segment at the score line. Dispose of the broken piece safely.
Extend the newly exposed sharp segment and continue working. Repeat as needed until all 13 segments are used, then replace the entire blade.
