IMHO BM710 is a modern version of Buck110 standard by which other knives are judged by, both have great blades but handles could use better ergonomics!
I have black D2 SE version, bought new from ebay.
When it arrived it had 2 tiny rust spots on cutting edge, 1 minute of scrubbing with dish washing green scotch bright pad and it was gone!
After that I didn't like factory toothy edge, so I done 5 strokes per side @15DPS on KOWS belt sander with medium belt, that produced smooth but still toothy edge!
It cuts great as is now but because it's SE I will soon put mirror edge on it for even better slicing!
Black coating now has minor barely there shallow scratches on it, from cutting card board. Which is very disappointing, because same cardboard left no scratches on ZT's black coating
4" blade with shallow recurve partially serrated is perfect size and shape for 95% of cutting tasks that I use it for!
You get maximum cutting edge available in smaller package, no wasted useful edge on stupid finger choils on small blade!
I always have smaller 3" blade for smaller more delicate cutting tasks, if I need it!
It has near perfect 50/50 blade 2 handle size proportions, max blade 2 min handle!

I personally hate tiny blades with huge two hand handles

My philosophy is give me max blade with min handle!:thumbup:
Weight wise it's very light, but doesn't feel flimsy! I wish other manufactures would take lesson from that, you can have strong but lightweight knife in one package!
It's very easy to carry most of the time you forget you have it on you!
Axis lock is now my favorite, but SOG's ARC lock is even better easier to use/deploy! the only thing I would improve is make easier access in scales by rounding hole edges around axis button!
Biggest issue I have with this knife is it's handle. While flat slim G-10 scales are great for pocket carry, lightweight and slim it isn't that great for prolong use in hand!
It's not very ergonomic compared to say Doug Ritter BM that one has much better more comfortable handle. Admittedly, I never held DR BM in my hand just judging from all the pics on this board!
I do standard test on all my pocket folders by cutting card board and kitchen food prep!
This gives me constant against which to compare knives design and material performance.
Prepping veggies will quickly tell you how good or bad really knife is at cutting!
Conclusion of test:
Pros: narrow, thin blade shape would be great for stabbing, slicing both push and pull is great, serrations are awesome, recurve sweet spot is in perfect location, creates paper thin see through slices, light weight means can work for an hour no problem!
Cons: square, thin, flat, narrow handle with sharp edges, isn't very comfortable for prolong use will give you hot spots in the palm of your hand, egg/oval shape scales would have been much better choice for it, it's not very safe for stabbing into hard materials, lacks index finger choil for better safer grip, I'm afraid hand can slip onto edge if covered in fluids! Doesn't have deep pocket clip, OEM clip makes handle stick out of pocket too much for my taste! Can't change pocket clip to tip down carry which is my preferred choice!
Conclusion:
It's my favorite EDC but it will need eventually, custom oval scales with index finger choil to really fit my hand with deep pocket clip to be perfect for me
