Crasical

I've been using Wood/Paper/Iron for handle/guard/Blade, or just Wood/Iron for the pan and sign. To my understanding, Diamond only increases durabilty, not damage. I suppose after the nether, when nether alloys and lots of quartz is available, they're fine, but the weapons you can craft when just starting the game seem distinctly inferior to vanilla equipment.

The weapons I've made in Tinker's Construct so far seem kinda under-powered. I've crafted a rapier, sign, and frying pan, and they all seem to only be doing 1-3 or 3-5 damage. Considering how easy it is to make a Diamond sword and a shield and do vastly more damage AND be better protected... Are these working as intended?
