>>419664>Trail blazing, shelter building, tree surgery, clearing shooting lanes etc.I'll hand it to you on these, the sharper blade is somewhat better suited. Even then I'd want a bush axe. If you're trail blazing you're obviously staying in an established camp, so you can have a bush axe, pic related.
>stocking firewood, landscapingAre you felling trees or something? Seriously, the axe/hatchet is going to outperform every time here, especially on the firewood. If you're cutting green firewood that means you're putting it up for next year, and processing WAY more wood than you should want to with your knife. It will take far more time and energy than a hatchet/axe will.
>It takes longer for the entire edge of a bigger knife to get dullIt's FAR easier to dull a knife than a hatchet/axe though.
