Boker fixed blade hunting knife

Gorgeous boker fixed blade hunting knife. Razor sharp and ready to go. Bought about 12yrs ago at 159 at the time I believe. I thought I'd like it but it's too big for me. I'd rather a smaller fixed blade more versatile I think. I'm looking to get 125$ or a trade for a .177 air rifle. Doesn't matter the model as long as it's a break barrel and soring powered.
