Irwin 66305SL – Frequently Asked Questions

1) How many pencils come in the Irwin Strait-Line 66305SL carpenter's pencil box?
One box of 72 medium-lead carpenter's pencils, ordered under part number 66305SL. It's sold as a set, not as a single pencil, so it suits crews or an MRO stockroom buying a season's supply rather than someone replacing one pencil.
2) Is the Irwin 66305SL a hard, medium, or soft lead pencil?
Medium lead, and it's a broad lead rather than a fine point. Sharpened to a chisel it gives a fine line for layout and detail work; used flat it lays down a coarse, high-visibility line for saw cuts on rough material like concrete or stone. If you only ever mark finish lumber, a medium broad lead is heavier than you need.
3) Will a carpenter's pencil roll off a sloped roof or a ladder shelf?
Not this one. The 66305SL barrel is oval, not round, so it stays put on a bench, a ladder top, or a pitched roof deck. That shape is the main reason trades buy a dedicated carpenter's pencil instead of a round office pencil.
4) Can the Irwin 66305SL pencil mark concrete and stone, or just wood?
It marks both. The broad medium lead is formulated to write on a range of jobsite surfaces, including rough concrete and stone for saw-cut guides, as well as framing lumber for layout. That makes it usable by concrete and masonry crews, not just carpenters.
5) Does the Irwin 66305SL carpenter's pencil come sharpened, and do I need a special sharpener?
The flat oval barrel of a carpenter's pencil won't fit a standard conical pencil sharpener; trades shape the chisel point with a utility knife or a dedicated carpenter's pencil sharpener. Budget for that when you stock the box of 72.
6) Are there batteries or any power requirement with this Irwin marking pencil?
None. The 66305SL is a non-energy-using tool with no battery included and no lithium cell, so there are no shipping restrictions tied to batteries and nothing to charge or replace.
