Even when these visible snags are removed, there’s still adhesive stuck on the blade itself but its hard to see. I clean mine blade with this adhesive remover, I also use it on scissors to keep them sharp. They make cleaner cuts when they are clean as well
Really true tip, Sometimes it starts to cut wrong and we just don´t take a moment to think it can be something as simple as that (time to use aluminium foil) or just recalibrate force.
