Samurai Dave, It's all up to what's value to you...
There are expensive custom knives that aren't worth beans and there are some cheap knives that simply cut like magic.
I like having a variety of knives to keep and choose from for various uses.
I recently bought a few Opinel's. I favor the No. 8. They really cut like magic and cost less than $10.00.
Buck 110, another good knife for only $30.00 or a custom 110 with BG-42 blade runs about $100 and it's as tough as a Sebenza. Actually, the Sebenza is delicate when you consider how easily the handle gets scratched and worn looking.
Bark River has some very sharp knives, hand made here in the USA...Check AG Russell's for their Woodland ($55.00) and Highland ($60.00) in canvas micarta. As good if not better than many high priced customs.
USMC knife by camilllus or Kabar, reliable, hold an edge and easy to sharpen or if you want a knife for prying and abusing, the BK7 or BK9 are as good as many customs designed for the same uses.
If you want a prettier knife that you can beat up, look at the Marbles Trailmaker, 10" 1070-6 carbon steel blade...very nice and very tough!
I stopped buying custom knives a few years ago. I found my expectations for a hand made custom knives are higher than most makers are capable of.
I'll never forget when I bought my last custom a few years ago, I waited like everyone does for their "one of a kind" custom hand made knife from a well known maker...I picked up the knife and was impressed until I was at home starring at my new gem and noticed that is wasn't perfectly symetrical...I could have returned the knife but I didn't want to offend the maker who had become a good friend. The knife is in my mother's kitchen drawer and it's a good user!
$400 could buy a lot!
