Katanas
Following the excellent advice of someone here i picked up the Mantis Warrior decals from Impatient Tabletop, which have the awesome crossed Katanas. I have done my army very much with a classic Romano-Greek theme with the crested helms and pseudo-latin names, but i fancy doing a single unit with katanas to match the decal, maybe put it on an Impulsor and have the unit jump out. Normally I'd just get such parts 3d-printed, but i thought with the new edition I might make an effort to play in-store and attend some tournaments, so need them to be official parts. Can anyone recommend any good sources of katanas/guides to making them for marines please? Thank you
