Hi all , i bought some ferric chloride to help etch the blade but after hearing about the concerns of it keep corroding the blade has made me think twice, and so ive held off , ive cleaned the blade a little more and heated it then used vinegar again , after leaving it for some time the blade turns a brownish colour ,once washed off it leaves a kind of patchy effect most the darkening effect on the out side of the blade leaving the centre pretty much untouched , ive repeated this process a couple of times but no signs of any twist core ,
i think its maybe to leave it now ?
Thanks for all your replies
