The Aerial Release model is our sixth featured Dalton of the
Week per Komodo's request. Here is the picture:
Overall Length = 8 - 3/4" Overall (including the skullcrusher)
Blade Length = 3 - 1/2"
"Aerial Release" is the correct name for this model, though I've heard it called the "Skullcrusher" due to its skullcrusher pommel. The blade is deployed and unlocked by pushing the bottom of the rounded triangular release forward. Pushing forward on the release pushes up on the backlock mechanism, which is similar to the backlock used on the "Thumb Release" model.
About 24 of this model were made around 1996. Based on the numerous variations in the handles that we've seen, it appears that these were probably hand made. All of the Aerial Releases had beadblast Titanium handles and beadblast blades. None were serrated. There were none with pocket clips that I'm aware of. There were a number of variations in the shape of the handle and the skullcrusher. The one pictured above has a hi-polish skullcrusher and release, while the others I've seen were completely beadblasted.
One thing unusual about the Aerial release is the thinness of the handle. Each side is about 0.120" thick, which is quite a bit thinner than any other Daltons that I can think of. Remember that the coil spring fits in a pocket in one scale and an opposing pocket in the blade. A normal Dalton spring is about 0.165" thick, consisting of about 3 - 3/4 turns of 0.040" spring wire. My guess is that the Aerial Release uses a special spring to accommodate the thinner handle. Here's an edge view of the Aerial release from the bottom:
