Comparison of base characters with characters describing the blade and point length, and thickness of cached points.

P-values (one-tailed) from Fligner and Killeen's [65] distribution-free two-sample test for coefficient of variations are shown.*Base character has CV that is significantly lesser than the non-base character using Benjamini and Yekutieli's [69] alpha correction; the critical value for 40 tests is α = 0.01169.1Measurements of base thickness (BT) were available for 50 of the 54 cached points.
