haha interesting , yes "diamond brand" the make copies of martindales products, hoes and machetes ect ect,, ive found their machetes normaly much harder than martindales and cannot be sharpened with a file..
normaly stiffer also... i remember when i lives in australia diamond brand goloks were common , . the quality varied greatly ,, but actualy several i owned were better than the original :O others were much worse..
it is interesting that there is not a firm producing masi knives anymore.. ive seen old english made seme blades.. but all ive seen were forged blades...
interesting machete
