What is the difference between the washer and ball bearing pivots?

Washers provide more resistance and tactile feedback when you open the blade, giving you a deliberate, controlled feel. Ball bearings reduce friction for a smoother, faster deployment with less effort. Both systems are included, and you can swap between them depending on your preference.

How difficult is S90V steel to sharpen?

S90V is a high-hardness steel with significant carbide content, which means it holds an edge much longer than common stainless grades but requires diamond or ceramic sharpening stones. A standard whetstone will take much longer and may not produce the edge you expect. Plan to use fine-grit abrasives and take your time.

Can I reverse the pocket clip for left-handed carry?

Yes. The clip is reversible for tip-up or tip-down carry and can be repositioned for either side of the handle. The two-screw design means you only need to remove the clip screw to make the change.

Does the titanium handle show wear from daily carry?

Grade 5 titanium will develop scratches and scuff marks from contact with keys, coins, and pocket seams. This is normal for the material and does not affect structural integrity. Some users prefer the worn look; if you want to keep the finish pristine, carry the knife separately or in a dedicated pocket.

Is the blade ambidextrous?

Yes. The dual thumb studs are positioned on both sides of the blade, so you can deploy it with either hand. The pocket clip is also reversible, allowing you to configure the knife for left- or right-handed carry.

Grade 5 Titanium Pocket Knife With S90V Blade and Dual Pivot System

Most everyday carry folders lock you into one pivot feel—either the hydraulic glide of bearings or the controlled resistance of washers. The Ti Manu includes both systems so you can set the action to match how you actually use a knife. If you open and close it a hundred times a day, bearings make sense. If you want tactile feedback and don't mind a deliberate deployment, washers are better. The two-screw design means you can switch between them in minutes without disassembling half the handle, and the S90V blade steel holds an edge long enough that the choice of pivot matters more than how often you sharpen.

Good gift when

People who carry a folder daily and want to dial in the feel
Anyone who values edge retention over ease of sharpening
Minimalists drawn to simplified mechanical designs
Knife users who prefer titanium for weight and durability

Skip it if S90V steel is harder to sharpen than common stainless blades, so if you don't have a fine-grit stone or a diamond hone, maintaining the edge will be frustrating.

No sizing to guess

The details

The Ti Manu is a folding knife machined from solid grade 5 titanium, designed around a streamlined two-screw construction that puts the pivot and pocket clip as the only attachment points. The handle is contoured to fit your grip without adding bulk, and the modified drop point blade uses S90V steel in a flat grind.

What sets this folder apart is the pivot system. It ships with phosphor bronze washers installed, but also includes ceramic ball bearings you can swap in. Washers give you more feedback and resistance; bearings make the action smoother and faster. You choose which feel you prefer without buying a second knife.

The blade deploys with dual thumb studs, ambidextrous and positioned to work from either hand. The pocket clip is deep carry, reversible for tip-up or tip-down carry, and machined from grade 4 titanium. The flat grind on the blade keeps the edge geometry simple and sharpening straightforward.

The frame is a single piece of titanium, shaped and finished to sit comfortably in your pocket without catching or adding weight you notice. The design reduces the number of parts and screws, which means fewer points of failure and less maintenance over time. A lifetime warranty backs the construction and materials.
