If you dont need it thin, get the handles, they are great and I love them. Turns the neck knife into a small fixed blade. If you wanna spend some money check out the knife connection, they have custome g10 scales. The izula is worth every penny. The knife with factory sheath can fit in some pockets and is pretty slim by most standards. Youll figure things out when you get it but you may want to look into custom kydex sheaths if you want something slimmer and more streamlined. Personally I would love a super small kydex sheath with no excess or even a slim leather sheath.
Btw, izulas are out in the blacl, desert tan, OD green, and pink in most places. Knives ship free has a special edition with an eagle (i have one), knifeworks has a safety orange one (i want one bad lol) and the knife connection has a limited edition American Freedom izula in blue with some special stuff. (i wouldnt really use it though, too special).
