Despite everyone's best efforts to get me to buy more chisels on Saturday, I only came away with this combination square. I never buy squares usually, but it appealed to me somehow - and I do seem to be in a metrological frame of mind at the moment. I got the general impression that the collective tool gurus present reckoned I was slightly off my nut buying it, but hey, a girl gets to the point where she needs to get her hands on something freshly rusted and painted-spotted, and this fit the bill all-too admirably.
A bit of TLC and elbow grease later, and a not displeasing result.
Nothing particularly special - as far as I can gather, Stanley churned No.21s out by the thousands over the years. But I like it; it feels good in the hand (and considerably better than the fancier, more expensive, and newer 12" combi square I already own - and never use as a result).
At some point I must find the patent and discover the purpose of the slot. I've got a vague impression of some sort of sliding bevel feature, but have yet to explore it fully. 'Cos yeah, I needed another thing that could do duty as a sliding bevel like I need a hole in the head. Or another chisel.
