The results are highly significant for the entire shape ( F = 55.22; df = 1, 98; p < .001), the haft shape ( F = 26.95; df = 1, 98; p < .001), and the blade shape ( F = 69.67; df = 1, 98; p < .001), and we confidently reject the null hypothesis of “no allometry” (full results in S2 Table 1 in S2 Table ).
