Just my preference but i like a rough surface better for stapes ... me 6 quid fencing hammers get a criss cross cutting with a cutting disc on the 4 inch..Estwing? I’ve got one, the softer grip is nicer on your hand after a days stapling compared to a £2 hammer, that’s about it really. I take a bench grinder to a hammer to flatten the face off for stapling and that makes more difference to the job
Trouble is stuff can get lost in the grass when out fencing , got a hayes chain strainer out there somewhere....
