Linder knifes are a german label made mostly in China as low cost/budget knifes. Some knifes have decend knife steels, but lack quality and proper heat treatment as you may exspect from the price. The fact that no steel is labeled on the blade leads to the assumption its made of some 420 Steel. Exspect the knife to be in the 10...15$ range.
The Linder Super Edge series fixed blades are really very good quality knives, but the company also brings to market quite a lot of substandard stuff that is better avoided.
