Hidden Blade Builders

Does anyone know of or themselves make props for cosplay or just working replicas of things. If so i am wondering if you have made or considered making the famous(i think its famous) Altair's hidden blade ASI Assasin's Creed. I am starting to think its way to cool for me not to make one, so ijust wanted to get some tips or better plans than what i have found.
