Yeah, Kizer flippers are great and they have a couple of Wharnie blades. One that comes to mind is the Rogue, but that blade is just a little over 3". A few Kizers that I've owned had weakish detents, which affects their flipping ability, so read up on individual models before you buy. Most of their more recent models have had adequate detents. If you look at their sub-forum here you can find a brochure from Blade 2016 with some really neat designs to come this year.
Also check out knives from Reate, CKF and WE. Off the top of my head I can't think of any with the blade shape you're looking for, but you never know. The best flippers I own are Reate built.
