As long as there is Mora Of Sweden there is no need to spend more than £10 pounds on a knife.
I recently read somewhere that Mors Kochanski said something to that effect. Something along the lines of, "If you spend more than $10 on a knife, you're wasting money." I tend to agree in certain cases.
I usually carry three main woodworking/processing tools in the field: a small fixed blade, a large fixed blade and a saw. My small fixed blades are always "cheap", but serve me very well. For a while it was a wood-handled Mora No. 1 with a leather sheath. I recently replaced it with a Marttiini "Black Lumberjack" that I picked up for 15 Euros and modified to suit my tastes (I'd post pictures, but can't seem to be able to..). Sure, I could go even cheaper, but I try to find a nice balance between having natural materials and a good price.
When it comes to the large fixed-blade choppers, I tend to spend more, because I have never seen a low-priced large fixed blade of good quality and natural materials that I liked and that could stand up to the abuse. So I use an 85 Euro YP Taonta leuku (or a Roselli leuku) for that purpose.
My saw is a 22 Euro Fiskars 10" slider.
If your Clipper serves you well, go on using it until the blade is worn down to nothing.
What matters is if it works for you.
