CJRB Kain J1956 Guide: Sanford Owen's 62 g Liner Lock EDC

The CJRB Kain J1956 is one of the few knives in this catalogue with a named outside designer attached to it: the listing opens with the line Designed by Sanford Owen (montereybayknives). It is a 2.95 in liner lock flipper that weighs 62 g in G10 or 66 g in aluminium, and all three of its published configurations are in stock at the same $39.99. That combination — small, light, one price, three build options — makes it a genuinely different answer from the 3.5 in budget flippers that usually dominate this price band.

CJRB Kain J1956 specifications

Every figure below comes from the single product listing for the model, which covers all three configurations.

Spec	Published figure
Blade length	2.95 in (75 mm)
Blade thickness	0.10 in (2.5 mm)
Blade material	AR-RPM9
Blade hardness	HRC 59-61
Blade finish	Stone wash / black PVD coating (one row for three variants)
Blade grind	Flat
Blade style	Drop point
Overall length	6.89 in (175 mm)
Closed length	3.94 in (100 mm)
Handle material	G10 / aluminium
Pivot assembly	Ceramic ball bearing
Clip material	Steel
Lock type	Liner lock
Weight	62 g / 2.19 oz (G10), 66 g / 2.33 oz (aluminium)

At 175 mm open and 100 mm closed, the Kain is a small folding knife rather than a compact full-size one: the blade is a little under 43 percent of the open length, and the 0.10 in stock is thin. Thin stock behind a flat grind is the recipe for a knife that slices cleanly, and 2.95 in of blade is plenty for a daily carry role. The trade-off is that a 0.10 in blade is not the tool for prying or for heavy cuts, which is a fair description of what almost everybody actually uses an EDC knife for.

Who designed the Kain?

The listing credits the design to Sanford Owen and references montereybayknives in the same line. In the store's published tag data, the Sanford Owen tag is attached to exactly one listing — this one — so as of this writing the Kain is the only Sanford Owen collaboration shown in the catalogue. Treat that as the brand's own attribution: the listing gives the credit and the handle, but no further background on the designer, so there is nothing beyond the credit that can be independently checked here.

Three configurations at a single price

Unlike most CJRB models, which split colourways across separate product pages, the Kain puts all three builds on one page and one price:

Configuration	Blade finish	Handle	Weight	SKU	Price	Stock
Black PVD / black G10	Black PVD coating	G10	62 g	J1956-BBK	$39.99	In stock
Stone wash / gray G10	Stone wash	G10	62 g	J1956-GY	$39.99	In stock
Stone wash / gray aluminium	Stone wash	Aluminium	66 g	J1956-GYA	$39.99	In stock

All three are buyable at the same price. The aluminium build is 4 g heavier, which is the only published mechanical difference between the two handle options — the blade, the pivot, the clip and the lock are identical across the range. Aluminium is stiffer and colder in the hand; G10 is lighter, warmer and textured. If you are choosing between them, the honest answer is that at 4 g the difference is a preference question, not a performance one.

How the Kain compares at $39.99

Several CJRB folders land on the same $39.99 price point, and they are not interchangeable. This table uses only figures published on the listings:

Model	Blade	Steel	Weight	Lock	Price
CJRB Kain J1956	2.95 in	AR-RPM9	62 g (G10)	Liner lock	$39.99
CJRB Pyrite-Light J1945	3.34 in	AR-RPM9	80 g	Button lock	$39.99
CJRB Feldspar J1912	3.53 in	D2/AR-RPM9	120 g	Liner lock	$39.99
CJRB Crag J1904 (carbon fiber)	3.43 in	D2/AR-RPM9	170 g	Liner lock	$39.84

The Kain is the smallest and by a wide margin the lightest of the four: the next lightest, the Pyrite-Light, is 18 g heavier, and the Crag is 108 g heavier. That weight gap is the real argument for the Kain. Nothing else here gets close to 62 g with a metal-lined handle, and the price is identical to knives that weigh nearly three times as much. If you want the biggest blade for the money, the Feldspar or the Crag is the better buy. If the goal is a knife that disappears in a pocket, the Kain is the outlier in the group.

Data notes from the Kain listing

• One blade-finish row covers three variants. The spec table publishes a single string, stone wash / black PVD coating, while the variant names split cleanly: two stone-washed knives and one black PVD knife. Go by the variant name rather than the row.
• Weight depends on which handle you pick. The listing publishes two weights and labels them by handle material, so the 62 g figure applies to the G10 configurations and the 66 g figure to the aluminium one.
• One page, three builds. There is no separate product page per colourway for this model, so the variant selector on the listing is the only way to compare the finishes side by side.

Frequently asked questions

How much does the CJRB Kain J1956 cost?

$39.99 for all three configurations, all currently in stock.

Who is Sanford Owen?

The listing credits the design to Sanford Owen with a reference to montereybayknives. That is the whole of the attribution shown on the product page.

Is the aluminium version worth choosing over G10?

They cost the same. Aluminium adds 4 g and a cooler, stiffer feel; G10 is lighter and warmer in the hand. Nothing else changes between the two builds.

Does the Kain have a button lock?

No. The spec table lists a liner lock, and the pivot assembly is a ceramic ball bearing — see Wikipedia on the liner lock and Wikipedia on ball bearings. If a button lock is what you want, the Pyrite-Light at the same price uses one.

Is AR-RPM9 a good steel for a small EDC knife?

The listing publishes HRC 59-61 for this knife, which is the usual range for AR-RPM9, the brand's own spray-formed stainless. General background on what steel choice means for a pocket knife is in Wikipedia on knife steel, and blade profile terms are covered in Wikipedia on blade geometry.

Is the Kain a good first folding knife?

It is a light, simple, single-blade liner lock flipper at $39.99 with a 2.95 in blade and a ceramic bearing pivot. Nothing about the published specification is complicated, and the size makes it easy to carry every day.

Where to start

You can see the model on the Kain collection page or go straight to the Kain J1956 listing to pick a handle. For context on the steel and the lock, browse the AR-RPM9 collection and the liner lock collection, or look through the new arrivals and the full pocket knife catalogue.
