Columbians get poo-poo'ed because they are usually lighter, per jaw size, than most other USA vises. Weight (mass) is important in a vise, however Columbians were made of heat treated malleable iron.
Their old ads claim the castings are heat treated for 11 days, resulting in a vise twice as strong as cast iron.
That is the reason it is an uncommon sight to see a broken Columbian.
