1. Yes. It is a MiniBuck, made by Buck, single blade folding knife, costs 15 dollars.
If anyone would like to see it and it's information this links to their page. Useful for anything that flat piece of metal is useful forl. Blade is fairly thick at non sharpened end which increases strength and number of applications
2. It's light, small, has a curved handle with well placed holes that make for a nice grip and prevent sweaty build-up. The plastic is extremely light and strong, and the blade is nothing special in it's material, and the way the handle is curved it is cleary designed to fit comfortably and securely in the palm.
