I am amazed at how active this forum is. You guys are awesome. I am new to this, and only have experience with a few steels (super blue, AEB-L, and garden variety stainless)
The Spyderco Gayle Bradley air looks great. Main concern would be the size, and lack of a lower choil; however, probably not too important on a light duty knife.
Was originally leaning towards the H1 steel ladybug, until I stumbled across the edge retention charts rating H-1 as category 8.
For sharpening, I will be able to sharpen at least once every two months. Most brittle knife I've sharpened and removed chips from is a sg-2 shun knife. Have diamond plates, ceramics and a wicked edge system.
Reason for wanting a supersteel:
1. Want to gift something that will still be on the cutting edge of steel technology decades from now. And I under the notion that M390 and CPM M4 are the 'best' and newest supersteels on the block.
2. Want an edge retention that is just absurd. Something that, even after a month, instills an awe inspiring sense of "wow, this thing is friggin sharp". For me, that means being able to shave arm hair with just the weight of the blade.
As for the knife being abused, she has experience using my super blue chef knife, and understands brittleness and toughness don't necessarily go hand in hand. She's likely to treat the knife well and not bang it around something hard, or scrape gum off a wall.
Summarizing recommendations and thoughts so far:
* Gayle Bradley Air
* Ladybug in H1 or ZDP-189
* Dragonfly in H1
* Squeak
