fantastic videos by the japanese hunter, actually i thought his english was real good. he's made a wiser choice to go with 3v alloy instead of s35 0r even s30. english catra tests last year rated the 3v about 30% more edge indurance than s30 .the 3v has a charpy index 3 times greater than a2 making it one of the most chip resistance alloys out there. some users have said that 3v seems to rust but my ferhman & lil canadian both in 3v have little patina after 2 years.cranky72
