Default stainless vs carbon steel

I'm new to putting stuff on fourums so if I do anything wrong please let me know. The reason carbon steel is so much better, & perferred by people who have knowledge of metalurgy, other than the rust resistance aspect of stainless is- carbon is needed to make the edge hard during heat treating so it doesn't roll the way stainless does. The reason stainless is hard to get sharp and keep it that way, is because when it gets thin it wants to roll to one side or the other. That being said Randall definitely uses a better grade of stainless alloy than most. The reason stainless doesn't rust as easily as carbon steel is that oxygen attacks carbon. The more pure alloy the stainless is like say 304 the less carbon content, therefore less rust. You just can't Harden stainless the way you can high carbon steel so the cutting edge is definitely less desirable. Just like everything else nowadays people like stainless for the ease of maintenance so you don't have to worry about it so much. I would think if you spend the money on a randal that you would want to take care of it and if you ever have to use it have a much more serviceable tool. You can actually make high carbon so hard and brittle during the heat treat it will break if you drop it. That is the reason a lot of high-end knife makers use high carbon steel for the cutting edge and laminate milder steel around it for flexibility so the blade doesn't break with use but will hold an edge for a long time. I have one that I skinned a deer, split the ribcage, & butchered it, you could still shave with it. Try that with stainless & you will likely stop sometime during the process to sharpen it probably more than once.
