The ALLWAY TOOLS HB11 is a 5-pack of No. 11 replacement hobby blades manufactured from carbon steel. The No. 11 blade profile features a fine, acute cutting angle suited for detail cutting, precision trimming, and insulation or material stripping in tight areas. These blades are a standard replacement consumable used by tradespeople and technicians who work with hobby knives for scoring, stenciling, gasket cutting, and similar fine-tolerance tasks. At 0.023 pounds per pack, they are lightweight and easy to store on a service vehicle or in a tool bag.
No. 11 hobby blades see regular use across HVAC, electrical, and plumbing trades for tasks requiring controlled, precise cuts on soft materials such as foam insulation, weather stripping, vinyl, and thin sheet goods. The sharp blade geometry allows technicians to make clean passes without tearing or deforming the material. The 5-pack format provides enough blades to rotate through during a service call, keeping cuts clean as edges dull.
Designed as replacement blades for most hobby knives that accept the standard No. 11 blade profile.
Blade replacement should be performed by a qualified technician using a blade removal tool or heavy-duty gloves to avoid contact with the cutting edge. Always retract or cap the knife before changing blades. Dispose of used blades in a puncture-resistant sharps container. Keep blades stored in their original packaging until ready for use.
