Thanks Abhijeet, I'd read that post before. It's good informative stuff.
Hey Olly, here's one of the blade after the thorough cleaning. Used 3M metal grade pad, and 000 steel wool, and some oil.
Now, while in Morocco, I did a fair bit of traveling and picked up a total of 9 blades. 6 of which were gifted. The one above, I kept, as well as a Touareg sword that I haggled for for over 3 hours and multiple rounds of mint tea and bread with a Touareg/Berber blacksmith. He didn't make it, he brought it over from Mali. But I did buy 6 small blades (5inch blades) that he made like the one at the bottom. Of those I kept the one in the picture and gave away 5. They make excellent gifts. These were all packed and shipped separately, and took quite a while to get to me (customs and all). But since I was cleaning that one up, I decided to get cracking and clean these as well.
Touareg sword. About 18 inches of blade, 30 overall. The blade had patches of light rust, and the bronze was turning as well. A good scrubbing with 000 steel wool fixed that. The blade pictures are before and after.
and after:
The Berber knife. Very crude, traditional western Saharan knife. The blade holds an edge very well, full tang. Sheath made of snake skin, camel hide and wood. The knife has scratches in it from the manufacturing process that won't come up with just a hand scrubbing. But seeing that its how their knives look anyway, I'm going to leave them there.
