>>6145455Here is a lineup for comparison.
#4 handle with #25 blade
#3 handle with #11 blade
Xacto fat style
Xacto thin style
I would recommend the #11's because they sit further up the blade than the #25. The #4 handle seems to offer less blade clearance in general, so I'd say stick with #3 handles, but I do want to try some of the non geometric blades like the #16 or #26, maybe #18, but as of yet I've only tried #25 and #11. #10a looks like a winner but they're not common to find from what I can tell.
They take a little time to get used to, I have a few I wrapped in heat shrink that I like over these, but once you get used to the flat scalpel compared to the round Xacto, it's a lot better. The profile is crazy different but you just change the blade every time you sit down instead of once every other kit or whatever. 100% recommend it.
