Bestech Platypus BG28A - D2 Sheepsfoot Flipper with a Grey G10 Handle

The Bestech Platypus BG28A is a 115.5 g work folder with a 3.43 inch D2 sheepsfoot blade, grey G10 scales and a steel liner lock. Open it with the index-finger flipper or the blade thumb hole over ceramic bearings; the straight edge and duck-bill profile are built for controlled push cuts, scoring and board work. Two-tone stonewash and satin finish, tip-up steel clip, and a backspacer that doubles as an improvised glass breaker. More folding knives and liner lock knives at EDCMALL.

D2 on a Straight Edge: Built to Keep Its Apex

A sheepsfoot puts a long, near-straight edge behind every stroke, and D2 backs it with some of the best wear resistance available at this price. At 59-61 HRC the edge resists abrasion through cardboard, rope and packaging far longer than any budget stainless, which is exactly what a scoring and push-cut blade needs. The trade is upkeep: D2 is stain resistant rather than stainless, so wipe it dry and oil it occasionally, and sharpen on diamond because the carbides skate on soft stones.

Frequently Asked Questions

What steel is the Platypus BG28A blade?
D2 tool steel, flat ground and finished in a two-tone stonewash and satin. D2 is a high-carbon, high-chromium semi-stainless run at 59-61 HRC - outstanding wear resistance, but wipe it dry and oil it because it is stain resistant, not stainless.

Why a sheepsfoot blade?
The straight edge with a low, blunted tip gives you maximum edge contact and control on push cuts, scoring and slicing on a board - and a tip that will not punch through what you are cutting. It is a workman's profile, not a fighter's.

How does the Platypus open?
Two ways: press the index-finger flipper tab as the knife clears the pocket, or push the thumb hole in the blade sideways. Both run on caged ceramic ball bearings and both work one-handed.

Is the tip really strong enough?
Yes - the spine curves down to meet the edge, so there is a lot of steel behind the point. It is not a stabbing tip by design, which is exactly why it survives hard daily cutting without chipping or rolling.

How does it carry?
Closed length is 4.81" (122 mm) and weight is 115.5 g (4.07 oz), with a tip-up steel clip set high so the knife rides low in the pocket.

D2 Tool Steel vs. Common Folding Knife Steels

Steel	Typical HRC	Edge Retention	Corrosion Resistance	Toughness	Sharpening Ease
D2 (this knife)	59-61	Very Good	Fair	Good	Moderate
14C28N	59-61	Good	Excellent	Good	Very Easy
Nitro-V	59-61	Good	Very Good	Better	Easy
154CM	58-61	Good	Good	Very Good	Moderate
CPM-S35VN	58-60	Very Good	Very Good	Better	Moderate
8Cr13MoV	57-59	Fair	Good	Good	Very Easy

D2 is a high-carbon, high-chromium tool steel rather than a true stainless - roughly 1.5 percent carbon and 12 percent chromium, hardened to 59-61 HRC on the Platypus. On a sheepsfoot that is the right call: the straight edge does push cuts, scoring and scraping, so it needs an apex that resists abrasion rather than one that flexes. D2 out-holds every budget stainless at this price, and the trade is upkeep - wipe it dry, oil it occasionally and sharpen on diamond because the carbides skate on soft stones. HRC figures are typical mill ranges, not a guarantee for any single blade.

Glossary of Key Terms

Bestech Knives
A Chinese production knife brand working with independent designers to deliver mid-to-premium folders with modern steels and tight manufacturing tolerances.

Platypus
Bestech's duck-bill work folder: a 3.43 inch D2 sheepsfoot on an 8.23 inch frame at 115.5 g, milled G10 scales, ceramic bearings and a steel liner lock.

Sheepsfoot Blade
A blade with a straight cutting edge and a spine that curves down to meet it at a low, blunt-ish tip. You get maximum edge contact on a straight cut and a tip that will not punch through what you are cutting.

Wharncliffe Edge
The straight-edge geometry that comes with a sheepsfoot profile: the edge stays in contact along its whole length, so push cuts, scoring and slicing on a board are unusually controlled.

Duck-Bill Profile
The wide, flattened forward section that gives the Platypus its name. It puts a lot of steel behind the edge and a broad flat on the spine for thumb pressure.

D2 Tool Steel
A high-carbon, high-chromium semi-stainless tool steel at 59-61 HRC here. Outstanding wear resistance for the money; wipe it dry and oil it occasionally.

Index-Finger Flipper
A tab at the blade tang you press with your index finger as the knife clears the pocket. The blade snaps out on the bearings and the tab becomes a finger guard once open.

Thumb Hole
An elongated hole cut through the blade near the spine. Push it sideways with your thumb to swing the blade open one-handed.

Liner Lock
A strip of spring steel inside the handle that snaps sideways behind the blade tang when the blade opens. One thumb of the closing hand releases it, keeping your fingers out of the blade path.

Ceramic Ball Bearing
Hardened ceramic balls held in a steel cage around the pivot. The action stays glassy and consistent for years, and ceramic will not rust or flat-spot like bronze washers.

Upper Jimping
The row of notches cut into the blade spine that gives your thumb a locked-in index point for controlled push cuts.

Backspacer
The block between the two handle scales at the spine. On the Platypus it protrudes far enough to work as an improvised glass breaker and carries a lanyard hole.

G10
Woven fiberglass cloth soaked in epoxy and compressed under heat. Light, rigid, essentially weatherproof and grippy when wet.

Flat Grind
Blade flats that taper in a straight line from spine to edge. On a sheepsfoot it leaves a thin, aggressive apex behind a lot of steel.

Two-Tone Finish
A blade finished in two treatments - a satin grind against stonewashed flats - so the grind line reads clearly and carry marks stay low-profile.

Who Should Buy the Platypus BG28A

• Tradespeople and warehouse workers who cut cardboard and tape all day.
• Buyers who want D2 edge life at a working-knife price.
• Anyone who prefers a straight-edge sheepsfoot for controlled push cuts.
• Collectors who want a duck-bill profile that stands out in a rotation.
• Gift shoppers buying for someone who actually uses their knives.

Who Should Skip It

• Buyers who want a fine piercing point - the sheepsfoot tip is deliberately blunted.
• Anyone who refuses to wipe down a blade; D2 will spot if neglected.
• Users who want a super-steel edge holder; D2 is the value pick, not the apex pick.
• People with small hands - the 4.81 inch handle is a full four-finger grip.
• Anyone who needs a left-handed clip; the Platypus clip is tip-up right only.

Care & Maintenance

• Wipe the blade dry after every use; D2 is stain-resistant, not stainless, and it will spot if you pocket it wet.
• One drop of light knife oil on the blade and at the pivot every four to eight weeks, then cycle the flipper a dozen times.
• Blow lint and grit out of the handle channel and the liner lock track before oiling.
• Sharpen on a diamond plate; D2's dense carbides skate on a soft aluminium-oxide stone.
• Keep the straight sheepsfoot edge flat on the stone and use full-length strokes - a rocking motion rounds the tip and lifts the heel.
• Finish on a fine ceramic rod or a loaded strop with light pressure - heavy passes round the apex you just set.
• Scrub the textured G10 scales with warm water, a drop of mild soap and a soft brush, then dry before pocketing.
• Check the pivot, backspacer and pocket clip screws monthly with the correct Torx driver.
• Never pry with the sheepsfoot tip - the straight edge is built for push cuts, not leverage.
