I recently bought a Fiskars, after reading reviews and threads here on the forum, to replace my beloved old CM trimmer which is out of production and for which I can no longer get blades. The new Fiskars uses Blade Style I and I bought the titanium replacement blades for it because they are supposed to be very sharp and last longer. I love this new trimmer -- wonderful accurate grid measurements on the bed and the swing arm is 15 1/4" (much longer than the old CM, plus the paper guide edge at the top extends all the way out on the swing arm. In addition to the rubber feet at the four corners, the under side of the bed is braced so it won't bend under pressure and there are 4 more rubber feet on the bracing. I think this will last a long time. I love it already.
