Just curious about history. Does anyone know when the spiral saw
(dremel, rotozip type of thing) first appears on the market? Or when
was it invented?

Don't recall the brand but there was a large version of this used in the
'60s and earlier in mass production of textile products--I remember seeing
one used to cut panels for parachutes for example.

If you can find the original Last Whole Earth Catalog you'll find it listed.
Was big, expensive, and definitely heavy duty compared to a Rotozip though.

They've since been replaced by laser cutters I understand.

I thought laser cutters only used for cutting sheet metals. Or do they
also cut wood panels?

Lasers can be used to cut anything that is cuttable. However I was
referring to the use in the textile industry.
