I don't really see why it is so important to use bike specific cable cutters to cut brake housing. If I just use standard diagonal cable cutters (everyday run of the mill kind) it might pinch the housing a little but nothing that can't be pinched back, right? And even if the cut is a little jagged, can't you just file down the ends?
Am I missing something completely, or am I right and park tool is just trying to scam me?
