At the start most peoples skill set is at a low level. Poor shaving technique, a misstep stropping and possibly dinging the edge on the tap or dropping a razor are all more likely than later on. So, like everyone else has said more at the start less later on. I think bluesman7's estimate of 2-4 rehones in the first year might be pretty close.

If you dive right in to honing at the start on top of learning to shave and maintain a straight razor with stropping you are in for a can of worms. I pretty much did that and it wasn't pretty for the longest while. Nothing associated with shaving with a straight razor is as simple or easy as it looks at first glance. It is also not as cheap as it looks at first glance either.

How you proceed is up to you.
