Hallem and Lt are going to have more experience knife fighting its kinda their bread and butter. Added to which in this case their are 2 of them. Against 1 of Bourne. Frankly Hallem vs Bourne is not a fight I see Bourne winning 100% of the time. Hallem is nearly as skilled and fast. Not to mention he has hight, weight, and reach on Bourne. Which does matter in close quarters combat. Now I'd still give Bourne the nod 1 on 1 vs Hallem, but with Lt in the picture. Bourne goes down.
