When I was young the most popular method of castrating calves was either cutting or using a burdizzo.  In the winter we would cut and the rest of the year we would use the burdizzo.  With the reemergence of the screw worm (I am in SE Texas) I am looking at moving back to the burdizzo.  Why did we stop using it in the first place?  Was it unreliable?

The vet I use also suggested moving to a burdizzo.

I am not really a fan of banding older calves as I have seen some issues with that.

Anyone else use a burdizzo?
TIA
