@ButtevilleBBQer - I was confused about the 18" bowl handles when I first joined the WKC also. You are correct in that the 18" bowl handles look like flat strap lid handles. The difference is there are no holes drilled in the bowl handle for the rivets of the wood handles and the lid handles are 4 1/4" wide where as the bowl handles are 3 1/2" wide. And yes, the 22" bowl handles are rounded.
You can see this difference between the bowl handle and the lid handle in the photos below.
Compare the bowl handle on this lime
to the lid handle on the cado posted by foshizzle. See the difference?
