I only own two dedicated bush knifes, the G Mills Timberwolf (few let downs and lost faith in the maker) and a mora companion heavy duty carbon steel.
To be honest, one is near 200 quid, the other was fifty (I believe the knife is 20-30 pounds but I bought it with a leather sheath and firesteel, which I'd recommend for you).
This is the version I got, although I shall also post the "nordic sheath" option which also comes with a DC4 stone for touching up in the woodlands.

Around 15 pounds more expensive but if you can find the items separately cheaper then do it, by no means am I spamming for TBS but its good value as you're only paying postage once.
When you can, I'd invest in proper bench whetstones, "ice bear" being my favourite brand, getting an 800, 1200, and a 6000+nagura will take any blade to silly sharp, especially with a strop at the end! Did this procedure with kitchen knives as a chef and craft knifes as a tinker, however its been much easier lately doing scandal grinds
Im by no means a bush knife expert but I haven't come across a task I couldnt do with a Mora, handmades and more expensive knives I think are more of a treat to ones self. Theres certainly someone satisfying in admiring a craft mans handwork. adds sentimental value too I think. Infact thats the only thing I don't like about the mora, it lacks soul!
