As a custom knifemaker, we regularly use step by step photo tutorials much like iforge does but photos, i have done several forging tutorials with a short to sometimes long descripton of whats going on in each photo this way, as they say a picture is worth a million and once posted in a thread everyone can ask questions ect and then perhaps the could be pinned for others to come to later. Id be willing to do a sheath tutorial on how i do it, make it fit the knife correctly ect.
