I’ll make the assumption that this shield is for SCA combat (Thorsteinn is an active member). I know very little of this period so I can’t comment on historical accuracy. The construction seems very solid and it should take a beating.
From a strictly SCA “sword & board” point of view, I like it very much.
Knees and below are illegal target areas, so simply keeping the bottom edge of the shield near your knee cop eliminates any low blows to your left (shield) side. Raising it slightly will block any high shots from a right handed opponent. Rotating it left slightly will block most wrap shots. The oval shape allows you a full range of attacks without being encumbered as you would be with a center grip round shield.
Unfortunately, you will have to find or make some type of hand & wrist protection. For those not in the SCA, even a center grip shield, with your hand inside the boss, requires you to wear hand protection. Why, I can’t say. It’s another one of our many silly rules.
