Today I tore out the carpeting in our living room, to clear the way for new laminate flooring this weekend. I used 3 of my EDC rotation, to test how I REALLY liked them!
I had to cut the carpet into 2' wide strips or my garbage guy complains and leaves stickers all over
Anyway I used my 154CM tempest, New Catapult, and my Ionfusion 110.
The room was 12' long. I could cut 1 strip all the way before I noticed the knife starting to dull and bite its way through the carpet with the Catapult.
The 154CM Tempest cut 2-3 strips before "feeling" dull. However with the heavy cutting and use the handle did not appear to be the most ergonomic and my hand got sore!
The Ionfusion 110 lasted 3+ cuts and I actually ran out of carpeting to cut so who knows how long it would last, also the handle seemed to be the most comfortable to me.
On the bright side

the Catapult was the easiest to get sharp again
I also must add that I dont know what kind of fibers are in the carpet but it left fine scratches in my black oxide catapult blade, almost like steel wool. Pretty abrasive stuff I guess.
