With just a polish the brass will stay shiny, if it dulls off you can touch it up with cotton wadding polish like Never dull or a quality billet metal polish like Peel or even Deep purple. All those products would have taken the thick patina off the torch like the little bit where the brand name was but i used the josco cut and polishing wheels on a bench grinder. I've got tons of other metal polishes that i've used to maintain the polished ally on the dish on the rims on my mazda lol so i can tell you whats good and whats notso i rekon with a bit of time and elbow grease that stove would come up a treat as well. What type of metal is it mate from ?? I've also got an old shoe iron that i got from my grandfather that i want to polish but don't know weather to leave it buffed with the cast pit marks in it or smoothen it out and give it a mirror finish lol
Looking at the logo in the pic that sanjia knife i got, your definitely right about the re branding thing, they probably do it to keep selling and making old designs that their more expensive brand doesn't use anymore. Same thing that tyre companies do with their popular molds
Thanks mate, most things that were made in the old days was meant to last so a bit of elbow grease and tlc brings them up to their former glory.
I was going to post the link earlier but John beat me to lol i rekon if you just search for hinting or survival knifes in ebay and start from the cheapest you'll find the same one cheaper then $7 or close to it lol
