We are in a knife forum, so it makes sense that the ability to sharpen ones knives is a respected thing. What I don't get is people who are irritated by collectors who don't sharpen. It makes your abilities a higher level. I sharpen all my friends knives because relative to them I am an expert. Those who can't sharpen, respect those who can, even if their knives aren't as nice as yours they are your superiors here in the knife world(IMO). At the same time, if you're good at sharpening don't get all uppity on others...
Now for the OP, I think it is best to start with cheaper things as you can meas up with less money lost. This doesn't mean the cheapest pos you can find is good, but you should be able to find a decent starter knife for under $30. In the long run though, different steels give different experiences and will make a more advanced sharpener who understands the process much deeper. I just don't see the need for people to rush into buying 100$+ knives. Yes they're nice but if its your first knife you won't know the dif between a Hinderer zt vs. a cryo. You'll always be able to spend more money in the future and the more you know when you do the more informed your decision will be.
