I think it's either testing the market as
@rje58 pointed out, or they are actively trying to curb demand because of supply issues.
Apple recently released their newest phone, the Iphone X, for a whopping $1k. This was about $200 above comparble phones from them in the past, as well as their competition. The reason they priced the phone so high, was to purposely curb demand. The AMOLED screens that they use in the Iphone X are made by Samsung (pretty funny) and Apple's supply is limited because first dibs go to Samsung phones. In order to curb demand and avoid a public outcry, they specifically priced the phone high enough to be out of the reach of most, with the intent to decease prices down the line as supply increases.
If we use that as the case study, it might be that Spyderco's manufacturing partner in Taichung is unable to produce integral knives in the quantities they require for normal runs. By increasing the price drastically, they have caused demand to decrease, and meet the anticipated supply that they will receive.
Food for thought...
