Sat down with a guy who has been laying brick in Baltimore for 30 years and he watched me clean my trowel at the end of a job, then told me I was scrubbing the handle and leaving mortar on the spine where it actually matters. Now I keep a small wire brush in my pouch and hit the spine before the mortar sets, and my trowel has lasted twice as long. Anyone else got a tool care tip they wish someone had told them earlier?
That Baltimore guy did you a real favor, I spent years scrubbing the wrong end of my trowel too and wondering why the edge kept pitting. Beating the mortar off the spine while it's still soft is the whole trick, wish someone had told me that back when I was starting out.
