My first (black) Pingo was almost 6 years ago. Since, Pascal has reviewed his (orange) Pingo… in his entertaining review Pingo Star !
I got the opportunity to get a very rare beast: a blue Pingo with K390 steel blade and studs to mask the tiny trademark hole and protect it from lint.

First I have noticed is the very firm and strong spring in this one, much stronger than my previous version. It is not the easiest opener with stud which is good as it keeps up its legal character: this is a two hands opening knife which can be open with a painful thumb. 😀

Now about the steel K390 is known to me as a friendly steel. I call it an hyper steel !

CHEMICAL COMPOSITION
C Si Mn Cr Mo V W Co
2.47 0.55 0.40 4.20 3.80 9.00 1.00 2.00

The numbers are talking for themselves !!
This is not a stainless steel with carbides forms from Vanadium, Tungsten and Chrome (which is not used for stainless purpose here)…
It will get a patina very quick on daily use (especially eating and cutting meat) and this patina will protect the steel even better. It will show some character in its legality.

What a beautiful tool ! It will be a beater as he name will be Bluebeat !

“Gazing into the heavens on a night as clear as ice
We held our breath
As a new jewel glistens in the Belt of Orion
Out to the west
And parked up on the ridge between all the different lands
I feel I’ve always been here
Do we go back to the city, back to the lights
To the unforgiven world or on into the night
Where there’s always something new to fall in love with
Searching after something new to fall in love with
There’s always got to be something new to fall in love with…”

Bluebeat New Model Army.

So again Spyderco has provided a non locking sub 3 inches spyder with one of the best super “engine” available hence the fun of using it hard!

It can disappear in the watch pocket. There is no reason to leave it behind !

Of course I needed to convex the edge a great deal as I know how stable this alloy is on thin edge. So no fears in making a real blue razor from it.
