01
Cut from the correct face
Traditional tools can create a back-beveled edge that resembles a natural split more closely than a smooth saw cut. Tool choice depends on thickness, texture, quantity and the visual requirement.
02
Protect the nail-hole zone
Holes need adequate distance from edges and the slate head. Poorly placed or oversized holes can crack during installation or service. Punching direction should leave the appropriate countersink for the fastener head.
03
Use templates for repeated shapes
Valley cuts, scallops and tapered turret pieces become more consistent with templates and control marks. Reject pieces that develop cracks rather than hiding them in a difficult location.
