Slip joints were and are made to be used by people who need a daily knife. As jackknife once said here our fathers and grandfather weren't underknifed. Those old slip joints (and new ones too) are just as applicable to daily use in our lives as they were to daily use in their lives.I really don't understand bemoaning (or even comparing) the two things. If you really want a fair comparison, you should compare the "golden-age" slipjoints to Kershaw, Benchmade, or Spyderco folders, as those are knives made to be used by people who need a daily knife. Slipjoints used to be made for people who needed a knife in their pocket; now they are made for people who like slipjoints.
