Welcome to the BladeForums!
First thing, there is a pretty big difference in size between the two. Both are very comfortable to hold, the blur is a bit grippier due to the Trac-tec inserts. Even though it is small, the shape of the Mojo's handle makes it quite controllable.
The blades will vary with the particular model of either. The Mini Mojo has been renamed the Mini Mojito, if the
born on date is July '07 or later the blade is Sandvik 13C26, anything before that and the blade will be 440A. This applies to the standard Blurs as well. There are also Blurs with higher end steels like the SG2 Blur pictured or S30V Blurs.
The Blur opens via thumbstuds, uses a liner lock and has no safety.
The Mini Mojo/Mojito has a flipper with an integrated safety. Using the flipper correctly disengages the safety, so the safety doesn't slow you down. It uses a stud lock - the thumbstuds engage a shelf on the handle to lock the blade. I have found it to be a very solid and reliable lock.
I have both and like them a lot. I EDC'd the Mini Mojo for a bit over a year and it was always a great knife, with no issues. Mine is 440A so I did touch up the blade regularly.
The Mini Mojo/Mojito has a lot of innovation in it, so it is definitely worth checking out.
I haven't had the SG2 Blur for all that long, but if you search the forum you'll find that it has had overwhelmingly positive reviews.
Everyone will end up telling you to get both, so I'll get it out of the way now.
Get both!
