BM 710HS Blade worn down - is it worth to regrind it?

Heck yeah. That bad boy will be awesome with a regrind. I sent a 710 to Big Chris and had him regrind it. Came back unreal. M2 is still awesome steel so I would keep it and do a regrind on it.
 
i sent my blade to lifesharp service and they took off the scratches incurred while sharpening.

although they took off atleast 0.5 mm of steel..(which makes a visual difference on a 3.45mm blade)

i heard u can also pay $25-$30 for a blade replacement

The 710HS blade stock was gone long ago. For replacement, the venerable D2 is the current option but it's not the same steel...that and just keep your eyes open on boards and eBay. Sometimes there can be surprises!
 
Thinning out the blade behind the edge would probably improve the blade's performance. As others have said, BM really got the M2 blades right. If the blade has been sharpened to a noticeable extent, a regrind (by someone who really knows what they're doing and won't draw the blade's temper) could be a real plus.

I have sold a lot of my BMs over the years but have kept the 710s and Ritter Grips with M2 blades. They really perform well.

The blade came back today. Much cleaner as before! I will have to polish the edge though.

Looks great man! To be honest if you're concerned about losing more steel, you should really hold off on sharpening/polishing until it's actually dulled down. Of course that's assuming that it came back to you sharp (which it looks!)
 
Yes, it is sharp :) and you are right: I will strop the knife and only sharpen it when really necessary.
I did so since I got it, but as I wrote in my first posting, it was well used in the last 10 years.
BTW I love the way the handle hold up. Looks almost like new.
