I wanted a One Hand Trekker with a smooth blade and I prefer a corkscrew over a phillips. I bought a Trekker and a Sentinel thinking the Sentinel would be a donor and I would live with the phillips. I procrastinated performing the surgery. Then I found a Forester M Grip which had One Hand, smooth blade, and a corkscrew. It also has dual density scales which Imdid not want. Seemed to me a scale change was far easier than brass “rivets” even though I am pretty good with mechanical things. So I ordered a set of Black and a set of Blue 111mm scales. I installed the black scales for now.
