I prefer the square bottom but do not mind (and own a few) pointed bottomed knit ties. The taboo isn't always intrinsic to the item itself, it is as often how you wear it.
This is how Drakes describes the wholesome goodness of their knits:
"Ties knitted on ancient wooden frames, authentic crunchy handle with contrast spots individually sewn by hand. The ultimate knit tie. Think of Michael Caine in "Get Carter"!"
