Actually a katana is typically not that great at inflicting huge cuts through muscle and bone. The spine is very thick and they are quite short. They are better at cutting soft tissue in a controlled manner with minimal force due to their very sharp but brittle blades.
depends of what brand of katana you are talking about. coldsteel makes incredibly strong blades. cold steel emperor japanese swords which are among the best http://www.coldsteel.com/japanimperial.html cold steel also the makes the norman sword that cuts really well http://www.coldsteel.com/norman-sword.html cold steel two handed sword which can slice a bull into small pieces http://www.coldsteel.com/twohandedgreat.html cold steel hand and half sword another good choice http://www.coldsteel.com/handandahalf.html also wkc a german manufacturer from solingen makes great katanas but if you look for the best then choose the tamahagane steel not cheap but a lifetime investment http://www.wkc-sports.com/JAP20BW2812.html
The strength isn't the issue, a katana is very thick once you get past the first few millimeters of the blade. They are also quite short for how much they weigh. A german longsword is vastly superior at cutting and can even cut a katana. Have a look at this, you will like it.
oh hemi you like coldsteel? i really appreciate their videos of the mans chopping meat and ice blocks with their wares have you seen the videos? post your favorite
