Something you may not have noticed in SNK
check out eren’s swords
ok now see this boxcutter? look familiar?
boxcutter blades get dull quickly, so instead of having to sharpen or replace the blade, you’re supposed to push it up a notch, and then take a pair of pliers and snap off the dulled segment.
so, not only are their sword blades removable and fully replaceable up to 8 times (with the spares they carry around), each sword can also be broken about 7 more times to re-sharpen the blade quickly in the middle of battle. plus, a genius little trick to make sure nobody’s blade ever breaks off in a titan and leaves them with something too dull or jagged to use.
so if you see them fighting in the anime with swords of different lengths? yeah, that’s intentional, and it’s a really really cool little detail.
