30-Degree Sharp Tip Utility Knife features a precise 30-degree tip design, ideal for fine trimming in narrow gaps and curved edges. The blade is manufactured from SK5 high carbon steel with anti-rust coating, delivering sharpness and wear resistance for long-term use in humid workshop environments. Equipped with an anti-slip handle, it prevents slippage during prolonged gripping. The sliding auto-lock mechanism firmly secures the blade to avoid unintended retraction during operation. The snap-off blade contains 8 break points; once the edge dulls, users can snap off the worn segment to expose a fresh cutting edge and extend service life. It adopts universally standard replacement blades for convenient procurement and exchange.

Lightweight and portable, this trimming cutter supports mobile operation on production lines. It delivers smooth, burr-free cuts to reduce secondary sanding work. The heavy-duty variant comes with built-in spare blade storage, and all models integrate a rear blade snapper for safe breaking of worn blades without extra tools. Widely deployed in shoemaking workshops, leather goods factories, EVA processing plants and packaging workshops, it trims leather cut pieces, EVA midsole flash, shoe lining edges, rubber trims and cardboard templates, suitable for shoe sample development and mass-production edge finishing of shoe uppers, shoe tongues, midsoles and leather accessories. The sharp 30-degree tip enables precise cutting on curved surfaces and confined spaces with neat edges, meeting stringent precision processing requirements in footwear manufacturing.

Before use, inspect blade locking status and sharpness. Slide the slider to extend the blade to a suitable length and lock securely. Adjust grip angle and cut steadily along material edges. Fully retract the blade after operation to prevent accidental scratches. Regularly clear blade debris and store the tool in dry conditions. For blade replacement, push the slider to the top to remove the old blade, install a new blade properly and confirm tight locking. To snap off worn segments, align the blade break point with the rear snapper and apply force to separate.

For daily maintenance, wipe dust and grease off the blade, clean internal handle dust weekly, and check slider smoothness and anti-slip layer condition. Replace blades promptly once they turn dull or develop notches; cracked blades are prohibited to avoid breakage and injury. Never point the blade toward others. Store the tool securely and restrict access to unauthorized personnel. Officially named the 30-Degree Sharp Tip Utility Knife, it is also known as leather trimming knife and EVA edge cutter, specially designed for trimming leather, EVA midsoles and other shoe materials. It processes genuine leather, synthetic leather, EVA foam, shoe lining, rubber strips and cardboard, compatible with thin lining fabric and thick EVA midsoles. The heavy-duty model offers higher load capacity for thick material processing.
