Laminating would definitely be the way to go. But if you can't do that and you wanted to knock down the sharper edges of the jaws just shim them open and run a strip of Emery cloth back and forth on the inner faces to smooth them down a bit. Don't want to make the jaw face any narrower tho. Just smooth the corners of the jaw face.
Poor planning on your part does not constitute an emergency on mine!

Sharp edges isn’t the reason for the laminations. Laminations add more surface area which serve two purposes. To give you more hold and to distribute the force felt on the animal when the trap closes. Those 650s are some pretty intense traps. I’ve been caught in all of my traps except my 650s. I’m extra careful with those. Getting themnlaminate didn’t that much more and it’s even cheaper if you do it yourself. If you’re worried about cost just get the 550s. Plenty of gold with those. Even the 450s have more then enough hold.
If traps work like the Antis say......I would have no fingers.

IT's a lot of trap not to have lams on. I'd find a way to add lams, personally. I'm very happy with my Cast Jawed models.
And lams don't aid in holding....it aids in cut/damaged feet. Ever coon trapper knows this.

And lams don't aid in holding....it aids in cut/damaged feet. Ever coon trapper knows this. If you look at physics, more surface area means more friction, which means more hold. The only reason the prevent cutting is because they are rounded. You could round any jaw and prevent cutting. Squared lams will still cause damage. It will be less but thats because the more surface area is creating more friction which means less movement between the paw and the trap, which will cause less paw damage.

I don't agree.This isn't a car tire on pavement.It is steel pressing in to flesh.Thin sinks deeper.than wide.It doesn't increase grip though there isn't enough difference to worry about.Wide distributes force over a wider area.That is it's purpose. Grinding with an angle grinder and smoothing up with a file works fine.Most don't realize how much that edge needs to be rounded,to make a difference.Emory won't touch it.The trapjaws have to be held open to get both edges.Both edges matter!Still,rounding the edges on an unlaminated MB650,will never stop the severe damage.They still cut and there will be bone damage. I get less damage with inside lammed '650's than cast jawed.Keep in mind,I round the unlaminated jaw edge on the ILs.The cast jaw edges are too sharp,out of the box.This can be fixed by grinding all 4 jaw edges,properly but who wants to pay $54 dollars more per dozen,to do that. The cast jaw also,does not have as wide a surface as the laminated models.Believe that! Inside Lams: Cast jaws:

About half of my 650s are IL/OL. There a full 1/2 inch thick. Much less paw damage compared to cast, even with red fox. I'll have to soften the cast jaws I have but when I buy more I'll get the IL/OL over the cast.
Common sense catches alot of fur.. Pay homage to all you harvest..

Your 100% right , 650’s need lams ! I’m not sure if flapper disc is accurate, I’m talking about the flat disc made up of multiple layers of sand paper for a 4 1/2” angle grinder . At any rate hopefully the OP will do some checking it only costs about 9 bucks for a lam kit from F& T ! It is actually cheaper to replace the jaws though the MB650 is a pain to do that with.

This post has me scratching my head. Now if the animals paw is it the trap and not moving. WHY would rounding the inside of the jaws be beneficial ? I think you'd be diminishing of the holding power. 'V' Plus, some will debates this , i find i have less damage with square stock the round stock laminate ! The animal is moving all the time and there are movable joints in their feet and wrists.We aren't talking an inanimate object here.If your theory were correct,the MB550 would be a worthless trap and people would have to file the rounded edges off.It happens to be a very foot friendly trap,out of the box and holds extremely well. Holding power is not affected by removing sharp,factory,sharp edges It is more a product of trap design and lock up. Over 50 years of experience has shown me that knocking the sharp factory edge off,dramatically reduces cutting damage,with no affect on holding power.I always choose experience over conjecture when making any design changes.
