I have a very positive view for custom knives in general over the next 2-3 years driven by a good economy with an increase in higher end buyers for many styles of custom knives.
Hot:
EDCs 7.5" OAL and below- we have seen the popularity of these increase and I feel this is only the start.
Damascus- especially new patterns and processes as makers look for ways to distinguish their designs from the pack.
Higher End Tactical Folders- I look for the these folders to remain in favor especially with the younger buyers.
Stag - I look for high quality stag (especially amber) to continue it's popularity and even gaining such as a result of decreased ivory use.
Larger, Higher End Art/Collectable/Investment grade knives - driven by a favorable economy.
Unique and Exotic Wood Handles- Beautiful rare and exotic woods and unique salvaged woods (including historically significant examples) will gain in popularity (especially for higher end knives) as makers and collectors look for options for replacing their previous use of ivory.
Pre-Death Bob Loveless Knives.
Not, So Hot:
Elephant Ivory - is on the way out for good.
Mammoth/Walrus Ivory- Just too much negative press for most knifemakers to invest in inventory. I do feel these ivories will make a comeback down the road when they are better understood by the non-knife buying public. Personally, I'm not going to stop buying knives with Mammoth and Walrus.
Loveless 'Style' Knives- I believe the demand for this style knife may slow a bit from the increased popularity we've seen in recent years.
Old-School Forged knife designs - The desire for forged knives with old fluted disc guards and straight life-less handles will continue to decline. The jazzy and innovative forged designs with contoured/sculptured handles, engraving and new-school Damascus patterns that quite a few makers are creating now will continue in favor, especially with higher end collectors.
