Hello Michael D. and welcome to The Yard. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
As for the DMDC.
1. Blade Length is 5" with the choil the cutting edge is reduced two 4.00 +/- 0.1 in.
2. Blade width is 1.5 in.
3. I don't have a weight gauge, but from what I heard it should be around 10-13 oz. Fairly light.
I'm sorry I don't have any info regarding the Fallkniven. I don't own any.
