SIK Golf DW C-Series Armlock Putter

Blade Putter

SIK built its reputation on one idea, that loft at impact matters more than almost anything else in putting, and the DW C-Series Armlock is that idea taken to its logical end. The DW is SIK's double-wide blade, milled with the company's Descending Loft Technology face, which stacks four different lofts down the face so the ball launches consistently whether you deliver the putter with a little shaft lean or a lot. Pair that face with an armlock setup and you get a putter aimed at players who want to take their hands out of the stroke entirely.

Armlock putting was having a moment in 2021, largely because Bryson DeChambeau had just won a U.S. Open with a SIK armlock in his hands. The DW C-Series version is the wider, more stable take on that formula. The shaft braces against your lead forearm, the grip runs long, and the loft is built to account for the forward press the style forces on you. It is a committed choice. You do not casually try armlock putting, and SIK did not build this head casually.

One thing worth knowing up front, there is no alignment aid on this putter. No sight line, no dot. For a putter designed around a locked-in, mechanical stroke, that is a deliberate call. SIK is betting you aim with the topline and the face, not with paint.

Design

The DW shape is a blade that borrowed a mid-mallet's footprint. The double-wide body pushes mass back and out from the face, so it resists twisting better than a traditional heel-toe blade while keeping the clean, squared-off look blade players want at address. The milled DLT face is the real story though. Four descending lofts, from more loft low on the face to less up high, mean your launch stays consistent even when the armlock press delivers the face leaning well forward. The mid toe hang is an interesting spec for an armlock. Plenty of armlock putters go near face-balanced on the theory that the anchored forearm removes rotation. SIK left some hang in the DW, which suits players whose stroke still works on a slight arc even with the shaft braced. If you swing the putter rather than shove it, this head will feel natural instead of resistant.

Who It's For

• Players committed to armlock putting who want a wider, more forgiving blade than the typical thin armlock heads.
• Anyone whose launch and distance control fall apart with forward press, since the DLT face is built specifically for a delofted delivery.
• Golfers with a slight arc in their stroke, because the mid toe hang rewards a putter that releases a little rather than one held dead square.
• Confident aimers who do not need a sight line, since this head gives you nothing but the topline to work with.

Frequently Asked Questions

Is the SIK DW C-Series Armlock legal under the Rules of Golf?

Yes. Armlock putting is legal because the grip braces against your forearm rather than anchoring to your body. The anchoring ban that took effect in 2016 outlawed belly and chest anchoring, not the armlock method. You just cannot press the club or your gripping hand against your torso.

What is Descending Loft Technology and why does it matter for armlock?

SIK mills the face with four lofts that decrease from the bottom of the face to the top. Armlock setups force significant forward shaft lean, which strips loft at impact. The DLT face compensates so the ball still launches on a consistent, rolling trajectory instead of getting driven into the ground.

What length and loft should I expect on the armlock version?

Armlock putters typically run around 40 to 42 inches with noticeably more static loft than a standard putter, often in the 5 to 7 degree range, because the forward press removes several degrees at impact. SIK builds the armlock DW to those armlock norms rather than standard specs, and exact numbers depend on your fitting.

Why does an armlock putter have mid toe hang instead of being face balanced?

Even with the shaft locked against your forearm, some players still rotate the face slightly through the stroke. Mid toe hang works with that motion instead of fighting it. If your armlock stroke is truly straight back and through with zero rotation, you might prefer a face-balanced option, but many converts keep a small arc.

Is this the putter Bryson DeChambeau used?

Not exactly. Bryson putted with a SIK armlock during this era, which is a big reason the brand and the method got so much attention, but his gamer was based on a different SIK head shape. The DW C-Series Armlock applies the same DLT face and armlock build to SIK's double-wide blade.
