Equipped with a bolster lock, elongated thumb hole, and smooth flipper for ambidextrous operation, it supports both thumb flick and reverse flick deployment. A precision-machined titanium pocket clip with integrated ramp ensures hassle-free carry. Designer Derek Sharon's vision balances timeless styling with precision machining, making the Lichen perfect for urban everyday carry and outdoor utility tasks.

154CM Blade Introduction

154CM is a high-carbon stainless steel that offers an exceptional balance of wear resistance, toughness, and corrosion resistance. Originally developed for industrial turbine applications, it provides excellent edge retention and a high degree of hardness, typically reaching 57-61 HRC. While it excels in versatile daily use, its primary drawback lies in its moderate difficulty to sharpen compared to lower-grade steels and its slightly lower corrosion resistance when contrasted with modern nitrogen-based alloys or CPM-S30V. Nevertheless, it remains a premium standard for heavy-duty folders.

Kansept Lichen T2091A3 - 154CM Drop Point Bolster Lock Folding Knife

The Kansept Lichen T2091A3 is Derek Sharon's take on the classic bolster folder: a 3.02 inch 154CM drop point blade with a flat grind and a stonewashed finish, hung on a fully chamfered twill carbon fiber handle. It locks through a fully ambidextrous bolster lock and opens two ways - thumb flick or reverse flick - on an elongated thumb hole. At 7.02 inches open and 99.8 g (3.52 oz) it carries like a much smaller knife. More folding knives at EDCMALL.

154CM Stainless: What the Blade Steel Does for You

154CM is the classic American high-carbon stainless, hardened to 58-60 HRC on the Lichen. It will not win a wear-resistance contest against a high-vanadium super steel, but it balances edge retention, corrosion resistance and toughness better than almost anything at the price - and it sharpens on ordinary bench stones without argument. On a knife that rides in a pocket next to sweat all day, that balance is worth more than raw CATRA numbers. Compare it with CPM-S35VN, Nitro-V and D2 tool steel - or browse every 154CM knife in the store.

Best Uses for the Lichen T2091

• Office and city carry where a traditional-looking folder draws no attention.
• Breaking down boxes and opening packages - the drop point belly does the work.

Frequently Asked Questions

What steel is the Lichen T2091A3 blade?
154CM stainless at 58-60 HRC with a flat grind. It balances edge retention, corrosion resistance and toughness, and it sharpens easily on a water stone or diamond plate.

What is a bolster lock?
Instead of a lock bar hidden inside the liners, the bolster itself pivots into the blade tang. It gives frame-lock strength with the look of a traditional bolster knife, and both hands can release it.

How does the Lichen open?
Two ways, both from the elongated thumb hole: push it sideways with your thumb for a thumb flick, or pinch and flick the handle away for a reverse flick. No flipper tab.

Is it left-hand friendly?
Yes. The bolster lock releases from either side and the thumb hole is centred, so left-handed users get the same deployment and closing as right-handed users.

Is 3.02 inches legal to carry?
Blade length limits vary by country, state and city - some jurisdictions cap at 3 inches. Check your local rules before you carry it; 3.02 inches sits just over the common 3 inch line.

154CM is the classic American high-carbon stainless: roughly 1.05 percent carbon with chromium and molybdenum, hardened to 58-60 HRC on these blades. It will not win a wear-resistance contest against a high-vanadium super steel, but it balances edge retention, corrosion resistance and toughness better than almost anything at the price - and it sharpens on ordinary bench stones without argument. On a folder that rides in a pocket next to sweat all day, that balance is worth more than raw CATRA numbers. HRC figures are typical mill ranges, not a guarantee for any single blade.

Glossary of Key Terms

Kansept Knives
A Chinese production brand working with independent designers to deliver mid-to-premium folders with modern steels, tight tolerances and machined hardware.

Lichen
Kansept's nature-inspired bolster lock folder: a 3.02 inch 154CM drop point blade on a 7.02 inch frame, a titanium pocket clip and a fully chamfered handle.

Derek Sharon
The designer credited on the Lichen. His brief was to make old and new work as one - classic bolster-and-scale lines cut with modern machining and a modern lock.

154CM
The classic American high-carbon stainless: roughly 1.05 percent carbon plus chromium and molybdenum, at 58-60 HRC on the Lichen. Balanced edge retention, toughness and corrosion resistance, and easy to sharpen.

Bolster Lock
A frame- or bolster-mounted lock bar that pivots into the blade tang instead of sitting inside the liners. It gives the strength of a frame lock with the look of a traditional bolster knife, and it is fully ambidextrous.

Drop Point
A convex spine that sweeps down to the tip, leaving plenty of belly behind it. The default all-round blade profile: strong enough to pierce, curved enough to slice.

Flat Grind
Blade flats that taper in a straight line from spine to edge. It slices noticeably better than a hollow grind and leaves more steel behind the apex.

Thumb Flick
Opening the blade by pushing the elongated thumb hole sideways and snapping the wrist. It works from either hand and needs no flipper tab.

Reverse Flick
Pinching the blade between thumb and forefinger at the hole and flicking the handle away. A fast, fidget-friendly deployment that works with either hand.

Chamfered Handle
Every edge of the scale is broken over with a machined chamfer so nothing digs into your palm during a long cutting session.

Titanium Pocket Clip
A clip machined from titanium rather than stamped steel: lighter, springier and corrosion-proof, with an integrated ramp so it slides over a pocket seam without snagging.

Anodised Aluminium
Aluminium given a controlled oxide layer by anodising. The colour is part of the surface, it resists scratching far better than paint and it will not chip.

Blackwash Finish
A dark tumble-and-etch treatment that reads near-black, kills glare and hides carry scratches far better than satin.

Micarta
Layers of linen or canvas compressed and cured in phenolic resin. It absorbs sweat and oil so grip improves with age instead of getting slick.

Twill Carbon Fibre
A 2x2 diagonal carbon weave laminated in resin: light, rigid, immune to humidity, with a visible depth that plain black G10 cannot match.

Who Should Buy the Lichen T2091

• Anyone who wants classic bolster-and-scale lines with a modern one-hand lock.
• Left-handed users tired of right-hand-only frame locks and clips.
• Buyers who want 154CM's easy sharpening instead of a hard-to-service super steel.
• Collectors following Derek Sharon's Kansept designs.
• A gift for someone who wants a pocket knife that looks like a pocket knife.

Who Should Skip It

• Users in jurisdictions with a hard 3 inch blade limit - this is 3.02 inches.
• People who want a fidget flipper tab; the Lichen is thumb-hole only.
• Anyone expecting a super-steel edge-holding champion at this price.
• Buyers who prefer a deep carry wire clip - this is a solid titanium clip.
• Hard-use campers who want a 4 inch plus blade for batoning and heavy chopping.

Care & Maintenance

• Wipe the blade dry after every use - 154CM is stainless, but pocket humidity still speckles bare steel over weeks.
• One drop of quality knife oil at the pivot monthly, then cycle the blade open and closed a dozen times to spread it.
• Blow pocket lint out of the handle channel and the lock recess before oiling so grit never grinds the pivot.
• Sharpen on a diamond plate or a 1000-grit water stone; 154CM at 58-60 HRC grinds predictably and takes a keen working edge.
• Finish on a fine ceramic rod or a loaded leather strop with light pressure - heavy passes round the apex you just set.
• Keep a consistent 15-20 degrees per side and deburr on plain leather before you reach for the compound.
• Scrub Micarta, G10 and carbon fibre scales with warm water and a soft brush; packed lint dulls the grip texture.
• Anodised aluminium is a surface oxide, not paint: keep it away from abrasive pads and harsh solvents or the colour will dull.
• Never pry, twist or use the tip as a screwdriver; side loads snap tips far faster than cutting ever will.
