美国正品进口Black Jack knives黑杰克BCB7BS黑色米卡塔柄A-2钢缎面刃双翼护手格斗博伊刀 编号：BC000557

        Blackjack Knives, no gimmicks just performance, and they are all sharp and American made. Hand crafted in the style of Randall knives using top quality steel (mostly A2 tool steel) and handle materials. Although these knives are not cheap, they are truly bargains because of the high level of materials and craftsmanship in each one.

        Currently being produced by Knifeware, established in 1998 by Ken Warner, a member of the former Blackjack team that was located in St. Elmo, Illinois. This brand makes superior cutting instruments, not wannabe gadgets or built-to-a-price ordinary dull knives. Blackjack knives are more than razor-sharp out of the box, hand-finished with edged convex blades crafted from tough carbon tool steel and superb handles fit against aluminum fittings. While making an excellent hunting knife and fix blades, a few classic Blackjack models are still offered by the company, including the Model 1-7, Model 1-5, and the ever popular Trailguides.

        Blackjack knives are built of very high quality standards, and in many aspects rival custom cutlery available today. If you want genuinely modern high-tech belt knives, they are here. If you want sturdy unobtrusive good-looking working companion knives, we got 'em. If you like the American Classic styles, this is the place. Small, medium, large, really big --- we got 'em.

        BlackJack knives这款格斗刀采用A-2工具钢锻造，具有强悍出色的性能和韧性，而合适的尺寸使得用户能更好的使用操作。

        刀身采用具有多样功能的博伊刀型，这种刀型无论是穿刺格斗，或者精确切割都非常合适。刀头的假刃设计便于刺入，而刃部以精细地极幼开锋手法进行打磨，锋利的刀刃拥有出色的切割力。刀面采用细腻的缎面抛光手法，光滑的刃面易于清洗，又降低了切割阻力，使用者可以更加精准地掌握刺划、切削的角度和方向，更好地用来处理食材或剥离动物的皮毛。

        A2钢

        A2是一种优秀的空气硬化钢，在强度上超过了D2和M2，但在耐磨损性能上稍显弱势。它最大的优势就是其赖以成名的坚韧性与打磨度，良好的延展性让它成为一些战斗刀的首选刃材。

        A2的铬含量在百分之4.75-5.50，碳含量在百分之0.95-1.05，因此经过热处理后的硬度可达HRC57。优良的耐腐蚀性和抗磨损性，并且有着很好的抗退火能力和抗张力性能。

        A2缺点也是显而易见的，5%左右的铬金属让它不易被切割，又因为是空气硬化钢，因此也无法进行分段冶炼。但瑕不掩瑜，还是有一席刀匠师钟爱这种钢，包括了手工刀界的传奇——Chris Reeve克里斯里夫以及现代凿刀研磨的先驱Phill Hartsfield。
