Do you mean to say that you think that the 0707 is "competitive" w/the 0452? If so, I think not.
The 0452 has a 4.1" blade (0.6" longer) and weighs 4.3oz (2oz more) than an 0707 at 2.3oz. Overall length of the 0452 is 9.27" which makes it look/feel more like a sword. The overall length of the 0707 is 8.25" but the design of the blade and it's light weight makes it look and probably feel more like a filet knife. Nothing wrong w/that but they're not the same.
The 0707 is more comparable in size & weight w/the 0450, which has a 3.25" blade, 7.375" long overall and weighs 2.90 oz.
Here's a pic of the 0452 and 0450 together:
The 0707 would fit between the two in terms of length and have about the same feel as the 0450 in terms of weight but with a sleeker/slimmer and more attractive design.
When you compare the 0707 w/the Sprint Run CF M390 Bareknuckle, they spec out almost identically w/the Bareknuckle's 3.5" blade, 8.2" overall length and 2.9 oz weight (same as the 0450) but the CF M390 Bareknuckle only retailed for $200 and one just sold a few days ago on the Exchange for $148.

The 0707 is a lot "prettier" and has 20CV steel (which is not all that better than M390) but if a CF M390 Bareknuckle can still be had $100 less than the price of the 0707, why bother w/the 0707?
On top of that you can buy a standard version of the Bareknuckle for just $73 on BHQ (I paid a lot more for one when it was 1st released) with obviously lesser 14C28N steel and just 1.3 oz more weight.
So, now that I've analyzed the 0707 to death, I think I've convinced myself NOT to buy it. No need to do so IMO as long as I already have a standard Bareknuckle which costs less than 1/3 the price of an 0707 and almost specs out identically with it.
Of course, there will be those of you that just "must have" the 0707.
Nothing wrong w/that either. Different strokes for different folks but personally, with all of the other knives I own, including the Bareknuckle and three 0452's (I sold the only 0450 I ever owned because I thought it was too small/light for a ZT), I don't see a reason buy it myself. At least not right now.
