Okay, well:
- I assume that's a typo and you mean Online dealer. You've had some recommendations already I think. The three which always spring to my mind are:
New Graham
(Mike seems pretty savvy to me. Goes that extra yard, has ultra competitive prices, great range etc)
1SKS
(Spark is of course our beloved board owner, also. Appears to have a peculiar anti-lawyer prejudice, but that's par for the course here. To be serious, he strikes me as being on the ball also - has a good operation etc)
Knife Works
(really good site, indicative of an equally good outfit, which others confirm)
There are other good ones of course. That TDE guy seems pretty decent also, for example.
Bear in mind these are large dealers who MAY not have as much time for you, in consequence. Another idea is to go to a smaller dealer you might be likely to form some kind of a 'stronger' ongoing relationship with (to make it clear, this might also be achievable with the larger ones anyway). Like EDC or American Heritage (for BM's). You'll find these and others here and on KnifeForums say (BladeTrader has a good rep for example), in the dealer pages. The thing is, you have email and a phone. You can get in touch. If you converse for a while, you can satisfy yourself about them and concerning the precise condition of the very knife you would receive, customs concerns, etc.
Also, although BM's have had variable quality in the past, recent reports around the place do suggest quite strongly that BM is really making more of an effort with this now. So to that extent, you can be more confident.
- the 705 is my favourite because I can use it more, given I live in a large Au city, my line of work, and so on. Aside from that though, the 710 appeals to me just as much - that is my Outdoor choice, for a folder. I think the two of them 'go together' somehow anyway.
- Steels are a massive can of worms. I'm out of time now and would only go so far with my thoughts on them anyway, if I can get back. At present, S30V is only available in one AXIS folder - the 921. BUT, there will be a 941 and a 73x in S30V (CF grips) (limited editions) released, soon I think. And more to follow, no doubt.
My suggestion would be the M2 710HS. M2 is TOUGH and BM does it well.
And look at this, if you haven't already -

Edited to add:
I've just seen MuskyHunter's posts on the 710HS. Given what he has to say and that he is in Canada, that should give you more comfort still.
