Who can tell more about this cleaver

[darkdream]

Hello,

Last week I tested a cutting edge 14.5 x 34' 4blade from a friend runs really well but if I check it on internet I only found a propshop that makes over the hub props like bravo.. Not high performance cleavers. My friend bought it from ebay so he don't have info about the propeller.
