Do not punch on hard objects such as hard rubber boards and wooden boards, which will damage the blade. It is recommended to use 4-5cm thick marble tabletop, with WUTA thickened cutting mat, which is quiet and stable, effectively protects the blade, and is not disturbed by the elasticity of the light desktop.\u003cbr\u003e\u003cbr\u003e3. As the force area increases, the resistance also increases. This is why large-sized punches are not as sharp as small-sized punches. It is not a quality problem. Before punching, you can use sandpaper to polish it to increase the sharpness (the punch also needs to be polished after the blade is worn out after long-term use).\u003cbr\u003e\u003cbr\u003e4. There will inevitably be slight rust and flaws on the surface of the punch, which will not affect the use. The rusted part can be restored by grinding with sandpaper. Please be careful if you mind!\u003cbr\u003e\u003cbr\u003e6. The surface of the punch is coated with a layer of engine oil to prevent rust. Just wipe it with cotton cloth before use.

First, be remember that when you punch large size punches，please use a larger, heavier hammer 20-24oz (560-680g)! Two, Before punching, you can use sandpaper to polish the blade tip to increase the sharpness (the punch also needs to be polished after the blade is worn out after long-term use).

This inherently creates greater resistance, requiring more force.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eForce Distribution: The force you apply is distributed over a much wider cutting edge area. While a small punch concentrates force on a tiny point, a large punch spreads that force out. To achieve the necessary cutting pressure per unit area on the leather, a proportionally greater overall force is required.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eBlade Thickness for Durability: Crucially, the cutting edge (blade) on larger punches cannot be ground as thinly as on smaller punches. An extremely thin edge on a large tool would be highly susceptible to bending, chipping, or breaking under the immense forces needed to cut through thick leather or dense materials. Thicker edges are essential for transport protection, durability and longevity.\u003c\/p\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eThis aligns with premium brands like Blanchard – they intentionally avoid ultra-thin edges on larger size punch tools because:\u003c\/p\u003e\n\u003cp\u003e✓ Thin edges would break under required force\u003c\/p\u003e\n\u003cp\u003e✓ Structural integrity ensures years of reliable service.\u003c\/p\u003e\n\u003cp\u003ePrioritizing a thinner edge for perceived \"sharpness\" would lead to rapid tool failure.
