How to know which is the 1h version, and which is the 2h version?
They're named exactly the same... 
It would be shnazzy if we were to give names to everything (like Blue Norman Shield, Green Normal Shield, Light Spiked Mace, Heavy Spiked Mace, Sugarloaf Helm, Sugarloaf helm with coif etc). It may seem a little trivial for basic items, but for those who are seeking the heirloomed versions, it matters significantly as a single mistake can cost you hundreds of thousands of gold (or in a select few cases, a million gold).
