I want to buy a new knife for my father. He enjoys case brand knifes but doesn't like to pay that much for a knife. I am willing to. I think he wants a two bladed knife with one blade smaller than the main one. Can anyone help me find something similar. I only could find the Texas Jack. Also could I see some size comparisons he likes a bigger knife. He only carries one knife and is really rough on them so the stronger the better. I would like to keep the price under 50 dollars but I am willing to go higher if I need to. Thanks in advance for all the help.
