[darter]

Well yes, I can explain without searching, why folks, I guess thats me, might use thin #11 blades to cut 2mm thick card.

The answer is so simple.

Normally I'd use a blade more suitable such as my box cutter on 2mm card, just like the ones in Looker's attached picture and probably the same as they use in Poland.

However there are times when the box cutter is not suitable.

I needed to cut some 2mm wide strips of 2mm card to make some 2mm square fence posts.

Not a bloody picture frame.

The heavier blades are too thick and caused the narrow card strip to become deformed making it unusable.

So it was necessary to gently cut with a thin #11.

By the way, I've been building wooden models including ships for 40 years and rarely used anything else but a #11 and I rarely have to change them due to not cutting anymore.

Perhaps I could buy a laser cutter with all the money I've saved building paper models rather than wood, metal and plastic.
