If you follow the Dangerous Things Scalpel link, you should consider a:-
x-Series = #11 blade (not shown in Picture), it is “stabbing blade”. these are great for making stab type or small precision cuts/incisions.
A #15 (Left) could be used…
But since we are discussing the subject
Flex = #15 (Left) but next closest would be a #20 circled (Right) probably a #10 next to that) #15 it has a small belly blade, these are good for short incisions which is all that should be required for a “standard flex”.
A larger “Disc Flex” you may want to look at a #20 or #10
FYI and dont ask me why
#15 smallest
#20 middle size
#10 largest
