SOG Pentagon...  Dagger (Photo:"SkaaRj" -

SOG Knives Collectors' Review/Take:
Here comes along another fantastic knife from SOG - the SOG Pentagon! A mean double edged (serrated and plain) dagger with a coffin-shaped kraton handle, this knife is suited to be a last-resort self defence tool to be hidden. Big brother of the Mini-Pentagon, this knife sports a generous 5" blade. There was a limited run of Cocobolo handled Pentagons in addition to the regular production Pentagons. The SOG Pentagon saw quite a long production life in SOG's inventory, testifying to its popularity. Older SOG Pentagons have the "square SOG logo" and the leather sheath that accompanies it. Even older ones have "EDM. WA" engraved below the SOG logo.

Do note that the SOG Pentagon is currently still being produced (under the same name without a '2.0'), but is done so in Taiwan instead of Seki Japan previously. The new ones can be differentiated by the SOG logo on the Kraton handle, a thinner blade of 0.125", and serrations that do not follow all the way to the blade tip.

Rarity index: 7.5/10 (10 being the most rare)
Rarity index scale (1 to 10, 10 being the most rare):
1 - Very common; easily available on ebay, google product search and almost every knife selling website. Spammed with at least 10+ listings on ebay.
3 - Has been around for at least 2 years and are selling reasonably well, with retailers favouring other newer models over this knife.
5 - Knives that are on the borderline of being discontinued or have been discontinued for less than 6 months
6 - Products from 6 onwards are either discontinued or limited edition.
7 - Discontinued knives that pop up once every few months on the "For Sale" part of forums or on ebay. Still can be found at a few online shops though.
8 - Knives that need lots of researching to find. Not available anymore in online knife shops and pop up (if you're lucky) >4 months for one at a time.
9 - Knives holding this rarity are the shadowy kind. You can't find any information on them at all (not even from online knife shops that have not taken down that knife's product page). If you see one for sale grab at all cost.
10 - The rarest of all knives. If you hadn't been here you wouldn't even have known that it existed. Should you have one of these you better lock it up in a triple-combination safe and treat it like a family heirloom...

Product Description:
Our new Pentagon sets the policy for action. Originally designed as a backup for law enforcement and emergency services, the Pentagon is the first multi-purpose double edge knife of its kind. The 5" stainless steel blade offers the instant choice between a serrated or bevel edge for cutting virtually any material. It's like having two knives in one! Twin thumb notches on the blade enables accurate blade orientation and downward control. The sleeky flared out wrap around checkered Kraton handle provides an optimum grip while maintaining a low profile signature. The stainless steel crossguard is custom solder fit to the blade, an unparaleled construction feature, for weather protection and strength. Housed in a black leather scabbard the Pentagon uses a heavy duty subdued clip for a variety of mountings. We think you will agree, that the Pentagon suceeds as an evolutionary achievement in cutlery!
