I've never been into the square tip but this http://www.ebay.com/itm/NWOT-Panta-New-York-Wool-Grey-Fair-Isle-Geometric-Stripe-AUTUMN-Knit-Tie-NR-P22-/311154925114?pt=US_Mens_Ties&hash=item4872475e3a#ht_4132wt_1362 makes me drool.
I bought this exact tweed while driving through Hawick this year. The options were amazing but I wanted something bold so that fit the bill, sadly I wish I had more room as one could have bought so much.
Spoo's sales of some vintage ties have had me at or above retail. In hindsight some of the auctions I've lost i should have been bidding well over retail as these items don't come back (ties most particularly). Shirts, suits and other clothing are common but ties seem to be produced and then they disappear.
