Exactly what did you put on the leather? It may end up doing more harm than good. Leather treatments can break down the leather`s cell structure and cause the leather to degrade. Plus it can cause the stamping to push out and be lost. I know from experience. While I never used any saddle soaps or leather treatments to soften or clean my leather items, I did use pure lanoline on a few items. I wish I had not now. It darkened the leather, left it oily feeling and looking, plus pushed out some of the maker stamping to the extent where it is gone.
There have been several discussions about treating leather here on the forum. I think the consensus is that the best thing to do is basically nothing more than wipe the leather off with a slightly damp cloth or paper towel. I now lightly spray Windex on a paper towel (not directly on leather) just enough to slightly dampen (not dripping wet) one section of the paper towel. I fold it in half and then in half again, then squeeze it in my hand to disperse the Windex though out paper towel. Then I wipe leather off. I do not scrub. Most of the dirt will come off the surface. I do not have to wait for the leather to dry because it is not wet (soaked) from anything. Then I use a clean soft cloth to buff out the leather to a degree, again not scrubbing but lightly wiping.
I hope your frog is not damaged from whatever you did to it. Time will (and does) tell.
Too bad about the grinding done on the blade. Looks like a nice bayonet other than that.
