Thanks for the Mustad info!
Thats the record of cutters I have managed to break off. I try to cut the sprue at an angle and leave enough material. It works in a way but is very hard on the cutter tips. One is a clean cutting but sensible sprue cutter from Barlows, the other two are rock solid pro tool shop merchandise. I admit I mix in 3-5% antimon though, my tin is pretty hard. Used a wild mix of hard and soft tin to be more exactly, just had a call with my metal dealer about purchasing antimon, soft lead and pure tin seperately so I can calibrate better. No need for too much hardness in a slab.
