Just bought an Ontario ASEK:
Here, the specs:
Hardness 50-54 HRC
Overall Length 10.25 in (26.0 cm)
Weight 1 lb 2.6 oz (0.527 kg)
Blade Length 4.95 in (12.6 cm)
Blade Material 1095 Carbon Steel
Blade Grind Flat
Blade Angle 60 Degrees
Blade Thickness 0.184 in (0.47 cm)
Blade Color Black
Blade Finish Zinc Phosphate
First impressions:
The knife came razor sharp. The grip on the rubber coated handle is simply fantastic. I just wonder why they don't do it more often.
The knife is handle heavy, due to the hammer/glassbreaker pommel (a feature I love). The knife sits very well in the sheath, which comes along with a additional tool serving as a belt cutter, flat head screwdriver and sharpening stone. All these functions seem to be thought through, and work very well.
I had some reservations regarding the low hardness. I guess the idea behind that is, that one should be able to sharpen the knife on a pebble if necessary and to prevent chipping or fracture when abusing the blade.
First tests:
Stabbing through metal sheet:
Though that sheet was rather thick, the knife did penetrate without major damage. However, the impact did blunt the tip minimally (the tip was really perfectly pointed before). Well, that was nothing that couldn't be handled with 600 sanding paper in less than a minute. I have seen worse results on highly respected blades like a Seki made Seal 2000 and a Kabar Bowie. Actually a had expected more damage due to the low hardness
Spine saw:
Unidirectional saw teeth are anything but perfect for wood. using the ASEK for sawing through green wood means lot of sweat, little effect.
However, sawing through fibre reinforced plastic worked very well.
The blade is partially serrated with very fine serrations. And though I'm not so much a friend of serrations, doing feathersticks for lightening a fire is really fun with that blade. As far as I can tell edge retention is not that bad.
It couldn't be more fuzzy.
First conclusions
pros:
- very good sheath plus extra tool
- fantastic and safe grip
- universal blade
- effective hammer and glass (or whatever) breaker
- saw works well on plastic
cons:
- not a chopper
- saw does not work on green wood
I still have to evaluate the edge retention in comparison to other knives, like i.e. an ESEE 4 or a Seal Pup.
So far, I really love the knife and it makes my favorite (urban) survival tool. For the woods I would still take my F1.
