I love how manufacturers have picked up on the sculpted scales thing. We used to pay Cuscadi loadsa money for stuff like that.
The Boker caught my eye too, the brokeback blade and Barlow type handle all looks really good. The last Boker knife I bought was the Atlas in polished stainless and it’s a tidy little EDC for light work, really slim.
But replacing a UKPK, that’s fightin‘ talk! One handed opening is essential, or certainly something I use so often I’m a bit lost without.
