I also altered my old American Angler knife blades so they'd work in the new fat handled Berkley knives ... you gotta take the plastic deal off the blades and then cut the slots out on the blades to match the slots on the berkley blades ... This is a photo of 3 blades I've done this to ... to date I've altered most of my blades so that they'll fit in the new knives. The blade on the left is a stock Berkley Blade set and the three to the right are the altered American Angler blades that now fit the new berkley knife.
This is my dremel tool with a cloth buff wheel I use to polish those blades sharp
These are my bars of polishing compound or rouge some dealers call it... the white is on top and it's a little more abrasive than the green ... the green is specifically for stainless steel polishing but it seems to be less abrasive than the white compound ... I just touch the polishing wheel to the bars until I get a good coat of compound on the wheel and then stick the wheel in the groove of each tooth then add more compound and go to the next tooth until I get each tooth saddle sharp and then to get the points sharp I use the cloth wheel on my bench grinder and apply the compound to it then lightly touch the blade to the 6 inch muslin cloth bench grinder wheel and get the teeth points sharp that way. I also have a bit for getting the teeth saddles a better angle or more drastic angle than they have from the factory so that they are easier to sharpen and stay sharper longer that way ... gotta be careful to not heat the blades up when doing this though and dip them in cool or cold water regularly to keep the blades cool ... i dip the blades about 3 to 4 times on each tooth when I'm altering the blade angles and a couple times when sharpening them with the felt or cloth wheels too. this maintains the blade's temper because if you don't keep them cool they'll be ruined and won't be any good to you at all
this is a bag of felt dremel tool polishing wheels 1 inch by 1/4 inch is what they're supposed to be but they're ticker than 1/4 inch and not uniform but doesn't matter ... I can cut them to fit down in the blade teeth real easily. Gotta be carefull when doing this so that you have the wheel turned the right way because if you have it turned the wrong way it'll grab the blade and hurl it or jerk it and you might cut yourself doing it.
the top blade is the one I used to alter the aa blades so they'd fit the berkley knives and the other two bits are the ones I use to alter the angle on the teeth so that they are at a sharper angle instead of about 45 degrees they end up being about 60 or so or a lot more in line with the blade instead of like a more blocky type angle they have when they come from the factory.
