Spyderco Endura 4 Signature Knife with 3.80" VG-10 Steel Blade with Emerson Opener and FRN Handle - PlainEdge - C10PGYW

同社デリカ4よりひと廻り大き目で通常のエンデューラー4と違い旧称エンデューラＴＳＵＮＡＭＩ（ツナミ）の形態をしています。　エマーソンデザインのブレードはポケットから出すときに「くいっ」と引っ掛けイージーオープンを可能にするウェーブ（と言う名の）形状。ジーンズ等で結構簡単に出来ますが、かと言ってやりすぎると端っこが擦り切れるので程々に。普通のパンツでは生地が傷み易いです。　タタンカ、ポリス、セントファンテ3等と同じくブレード材は表記の通りVG10。砥易いのに刃保ちが良い鋼材でヘアライン仕上も上等熱処理も素晴らしく、箱出し産毛剃りOKの流石　seki-japan　メイド。　一部輸入元の違いで刻印無しの物が有る様ですが、そこの真偽は販売元に問い合わせ確認等をして購入してください。　ハンドルは新旧あります。新ハンドルは写真と違いチェッカリングブロックが縦横整然と並び、ポケットクリップが金属製ランヤードホールと一体型高剛性化しています。デリカ 4　直刃　Spyderco Delica 4 C11PBKの写真を参考にして下さい。　但し新ハンドルはライナーが有りませんので横方向への外力に注意しましょう。　個人的には以前のなんとなく蛸っぽい並びのハンドルデザインも好みでしたが、まあそこはそれなりに。ただし仕入れ元の違いにより旧ハンドルが配送される事も有ります。旧ハンドルはライナー入りで僅かに重量がかさみます。ただ、その分ハンドル自体の精度強度が高そうで、ブレードとの擦れ合いも良く、ここにこだわる方は事前問い合わせが吉でしょう。また新旧ハンドル何れとも家に来た分に関してはブレードは前述の通り関-japanと確認しております。　　たまに　デリカ4ウェーブ　より安価になる事が有り、その時はこの上無くお買い得。

サムホールが有るので、ウェーブフックなど無くても機能的には問題は無い。無いのだが、やはり有った方が楽しい。鋼材、デザイン、共にすでに定評があり、何の不安も無い。使うためのナイフとして抜群のバリューが有ると思う。ウェーブフックはもちろん、エマーソンのパテントを取っている。

イメージ写真ではハンドルの色が黒に見えるが実際は暗い藍色になっている。しっかりとした剛性で箱出し状態での切れ味も申し分ない。エマーソンウェーブによるポケットオープンが滑らかで使いやすい。

*update* it's been over a year now**:It's somewhat difficult to pinpoint exactly what changed, but this is now the least used knife that I own, but it is still a REALLY good knife. Here is what I think happened:I bought a Benchmade Contego in M390--another large blade, with an even better steel, sturdier build, and better blade geometry for everyday use. (Also, 3x the price of this knife.) I also bought a Spyderco Dragonfly--an amazing little knife that I use anytime I'm afraid of scaring onlookers with the Contego or this knife.The Saber grind on this knife keeps it from excelling at cutting, and it's wobbly lateral flex diminishes using it for utility work where twisting and prying on its nice thick long blade would be helpful. So, this knife is relegated to defensive carry use where it still is the fastest deploying knife I own, with a blade designed for stabby stabby. The real problem here is the Kershaw Emerson knives. If you are going to put a non-working razor edge on a knife and carry it hoping to never need it, then the new Kershaw knives with crappier steel but sturdier build, actually do the job better for less money. Are the ergonomics as good? No, but they are good enough. And they are solid, heavy, and tank-like in their build. In my mind every positive of the spydy is met by a positive in the Kershaw, and you could by 3 of them for the price of this knife.In short, this is a nice knife, but in every area of actual usage, its design choice places it behind other knives. In utility work, edc jobs, its blade geometry makes it less effective, and its relative weakness to lateral stress is the nail in the coffin here. In defensive carry, while it's ergos are better and it's blade shape is perfect, sturdier builds and excellent blade shapes in cheaper knives at least equal the spydy.Final verdict: it's a nice knife that doesn't get used.Everything else I wrote still stands true, with the awe of owning a truly nice blade worn off and reserved for even more expensive blades. (Ain't that how it goes though?)This is an early review, having only had the knife for a day, putting a shaving edge on it, using the wave feature, and carrying it for a day doing light cutting:This is the first nice pocket knife I've ever bought. Prior to this, my nicest pocket knife was the Kershaw Needs Work. At only $20 more than the kershaw, this knife immediately shows itself to be superior in all ways except for what can't be judged because they are designed for completely different tasks. This fit and finish is better, and even though I really like the ergonomics of the needs work, and at first glance it looks like the needs work would have MUCH better ergonomics, it's just not the case. This knife is more comfortable to hold, has better grip, and sits better and more stably in the hand.The VG-10 steel blew my mind. I didn't expect that there would really be THAT much of a difference between a mid-tier premium steel like VG-10 and more common production knife steels from reputable companies like Kershaw, but I was dead wrong there. I'm instantly spoiled and fear I won't ever be able to stomach cheaper steel in a pocket knife again (in a machete or survival knife absolutely, but for a cutting tool that I expect to use regularly and want to keep a nice edge, no way--knowing what's out there and how nice it is I don't think i can go back). It takes a little more work to sharpen, but takes a wicked wicked edge far more easily. Freehand sharpening the near-shaving sharp factory edge for a couple minutes with a 1200 grit diamond hone left me with embarrassingly large bald spots on my arms.The Wave feature only took a little practice and is very easy to use or NOT use if that's your choice. It's easy to draw into a standard or reverse grip. I admit I've always thought the "spidey hole" looked ugly, and I figured would be more awkward to use than a thumb-stud...wrong again. It's easier, opens into a more usable grip than my Kershaw's speedsafe system (which is still quite nice!) and functions more forgivingly than a thumbstud.I feel like I'm rambling, but the bottom line for me is this: a knife this size, this well designed, with this much VG-10 steel, at this price is actually a fantastic value.If I had to complain it's that the blade is so long and handle so light that it feels like the knife MAY not stand up to much lateral flexing. I said may not, and I don't plan on testing it or using this knife to pry anything with, so this is literally no concern at all to me. It locks up tight, I love the frame lock, and I'm utterly confident it's a fine cutting, piercing tool. So far I'm blown away and loving this knife.

OVERALL: I already owned a serrated Endura but wanted something more self defense oriented. This works well for that purpose and is even the knife the founder of Libre Knife Fighting recommends. It arrives very sharp, and opens super quickly when it doesn't get hung up inside your pocket (more on that below). I like Spyderco's textured handles. They're light and offer good traction even with wet hands.COSMETICS: The grey handle looks a lot more like navy blue. It exactly matches my raw denim jeans. This was kind of disappointing because I was expecting grey and everyone knows that black and navy don't go together, but I suppose there are some functional benefits to it blending in with your pants.OPENER: The opener works well, as long as your pocket doesn't have any seams other than the cuff at the top of the pocket. 50% of the time, it gets caught on the bottom of the small change pocket in my front pocket. This would be a real issue if you actually needed to deploy it in a self defense situation. I clip it onto my backpocket to avoid this issue.VALUE: The price is a little steep compared to a normal Endura knife.
