These are aluminum.If you can't find one I think SK blades is supposed to be releasing an aluminum bolt together 110 with upgraded steel sometime. Don't think I've ever seen a timeframe though.
Where are they available from?There are now 6 different handle slab materials available for the Aluminum 110. Iron wood, natural linen Micarta, olive drab linen Micarta, red linen Micarta, Ivoroid, and charcoal G-10. Maybe we can get 6 blade choices?
