Review on 🔵 IRWIN Tools STRAIT-LINE 64499 Aluminum Chalk Line Reel, Refillable with 4-Ounce Blue Chalk, 100-foot Length by Marcos Olvera

The tool is made from durable metal and we've made sure the chalk in this set is practically useless. I grew up on a construction site, have done anything and everything since childhood, I know how to use a chalk line. This chalk is meant to be temporary, which is good, except it's temporary enough that it can be used on any type of plywood or wood, really, once you break the line and use the saw, the saw will blow off the chalk line, marks leave or whatever - something else that makes it pretty much useless when using an electric saw. It works well for roofing and laying lines for shingles, but not for cutting.
