You can do it with any level hammer, sewing kit, saw and fletching kit. I read on stratics of people using a saw to get 5 hci and then enhancing to get 10 but I have seen no pics so far. I have reforged a few items and have found better results using mid-tier items and then imbuing + enhancing after.
Doing so has allowed me to replace some arms resulting in mana regen 3, Stam 8, Mana 8, LMC 5(all I need) and 9 Kinetic Eater.
