The Bavli, Shabas 31 amud 1, has two stories in which a gentile came to Shamay asking to be converted to Judaism, upon which Shamay "pushed him with the construction cubit in his hand". Rashi explains that a construction cubit was a cubit-long stick used in construction for measurement.

Why did Shamay have one in his hand?

I heard once in a recording from R. Y.S. Schorr that Shamai represented a middas hadin, an exacting attitude of strict justice (as is evidenced by those very stories). His measuring stick was a display of just that point - everything had to be measured and exactly according to what was deserved.

+1, and thanks. Is that the one at Or Sameach (Monsey)? – msh210 Jul 28 '14 at 5:16
@msh210 Yessir. I bought the recording there, but you can find them at I think it was in either Parshas Korach or Pinchas. – yEz Jul 28 '14 at 5:18

The Chassam Sofer says that Shammai was actually a builder by trade. He wanted to show this apikores that there is more to religion than just kindness to your fellow, its possible to be a talmid chacham and a builder. Whereas Hillel said that you can learn on one foot, i.e. kindness, but don't forget that includes kindness to Hashem which means keeping His torah.

The Ben Yehoyada (in one explanation here), similarly, says he was a building-measurer by trade, and so carried a stick with him.

The Maharsha there s.v. על רגל אחת explains that Shamai was, in the two accounts in which he was holding the construction cubit (as he was not reported to be holding it in the first account), showing the questioner some important element of his response.

The fellow who asked to be taught the entire Torah on one foot was being shown that just as a building cannot stand on one pillar, so too the Torah has many mitzvos which cannot be given one simple foundation.

The fellow who asked to be a kohen gadol was being shown that the Torah does not stand on the pillar of kehuna (priesthood) alone.

I don't see how this answers the question. Okay, so if Shamay had a ruler, he pushed the fellow with it to show that the Torah is like a building. It doesn't explain why Shamay had a ruler, which was my question. (+1 on your other answer post, though, which does answer that question.) – msh210 Nov 2 at 5:43
@msh210 Maharsha points out that the Talmud is not consistent about him having a ruler - he had it in two of the accounts but not in the third. He seems to have taken the ruler for the purpose of making the point. – yEz Nov 2 at 5:46
ah, I see. Thanks! – msh210 Nov 2 at 5:48
