AISI 4130 steel is in the database now. Low alloy Cr/Mo steel, aparently used in swords and large knives, although given it's relatively low Carbon content I wouldn't consider it equal to other popular choices like AISI L6 and AISI 5160. Also added its German equivalent W-Nr 1.7218 steel with exact composition from DIN standard, which has even less allowed Carbon spec.

This time, it's the Crucible CPM S90V steel and Latrobe DuraTech 420PM steel. Not so sure how did they ended up in different reference groups, note on DuraTech 420PM said it was an equivalent of CPM S90V. Fixed now.

Added about half a dozen new compositions and about 40 new alloy names, including AISI 4142, AISI 4145, DIN 56Si7, DIN 55Si7, AISI 9255, DIN 67SiCr5 with corresponding names for various standards.

Spyderco ZDP-189 Endura 4 folding knife

After publishing the review, I was contacted by Spyderco fan, who had a few interesting comments regarding that particular review, and a few others things. I've updated the review with the information regarding one handed operation of the lockback mechanism, and added corresponding link with instructions and illustrations from Spyderco. I'm till not too hot on using one handed method myself, but the way I see it, it's better to know than not to ;) Who knows when it might become handy(I hope not).

Crucible CPM S90V steel and Carpenter CTS-20p steel are in the same reference group now, compositions are prety much identical. Same holds true for the Carpenter CTS-BD1 steel and Hitachi Gin-1 steel.

The other day I was going through my flashlights, and realized that I haven't had a new flashlight for ages. Unlike knives, flashlights involve electronics, chips and circuits, technology in other words, and those things progress much faster compared to metallurgy, at least as far as knives are involved. Sad but true. Did some research and picked up a few new lights. NiteCore EX 11.2, NiteCore IFE2, from LNFLUX series, 4Sevens QMini on CR2 battery and couple other lights that haven not arrived yet. LEDs are mucho better compared to few years back, and as you'd expect with tech based items, you get much better stuff for the same price. One thing I was really surprised about, how expensive some of the custom flashlights have gotten. Although the designs are more sophisticated and refined compared to few years back. Still, 500-600$ for a pocket light seems a bit steep, but hey, it's a custom, if you want something special may be it'll be the one ;)

Back then I was using Add This widget to allow sharing, but eventually I figured it was slowing down page loading, and there are quite a few scripts running on the pages besides sharers. Now all of them are static, except for the Google +1.

Had it for a while, finally decided to post the review. My first Spyderco knife ever, and sadly I didn't really like it. Nothing wrong with the knife, but the design doesn't really do ti for me. Suck, what can I say. Should've researched more before buying. Been collecting knives for 15years now, almost never happens to me, to buy knife based on photos and then be disappointed, but this time I really rushed with the purchase, and I figure you could say, paid the price. Still, as a folding knife, it's a really good one, if only the visuals were good...

The problem was with the alloy names containing # symbol, it was not translated correctly, there was no substitute to be precise. As a result, links in the steel chart didn't work correctly. Introduced ! as a substitute for the #, links work ok. Fixed similar issue with the steel directory listings, & was not handled properly.

Picked up one on BF trade forum a while back. Variation of the Busse Satin Jack knife. Super tough knife as all other Busse knives are, 1/4 inch thick chunk of steel, very nicely made. Medium size all around knife that can take on pretty much anything you throw at it. Obviously, Busse Battle Mistress is a better chopper, but it is much bigger too. Details in the review, follow the link.
