Your punch-down tool is working fine, but the blade's gone soft and you're getting ragged terminations. No need to bin the whole tool. This JAYCAR 110 Krone blade drops straight into the TH-1740 – hardened SNCM-21 steel, reversible, and you swap it by hand. No screwdriver, no fiddling. One end has a cutter for a clean, neat termination; the other is plain for linked blocks. Blade retaining pressure sits within 4–6 kg, so it stays put while you work. Add to cart and your tool's back in action
