The Four Sets on the Bench
Wera Kraftform Micro (~$75) — 11-piece set covering PZ, PH, TORX, and flat sizes. The defining characteristic is the handle shape: a three-zone moulded grip that places your fingers in the correct position for precision work automatically. Wera's Lasertip tips (laser-roughened for grip) are consistently the best at holding onto recessed fasteners.
Wiha 32802 Precision Set (~$65) — 12-piece, similar size range to the Wera. The handle is a more conventional cylindrical multi-component grip. More neutral feel than the Wera, better for people who rotate the tool in the hand frequently.
PB Swiss 860/7 CFS (~$130) — 7-piece set, the premium benchmark. Chrome-vanadium steel, machined to tolerances tighter than most other manufacturers. The handles are acetate — classic, handsome, with less grip texture than the German competitors. These are workshop tools, not household screwdrivers.
Facom 89-56-4 (~$95) — 6-piece set covering PZ and PH. The smallest set of the group, with the most aggressive handle grip texture. The Facom handle has the highest friction surface — useful when working with oily fingers or in warm conditions.
What We Tested
Three months, 200+ screws across four categories: laptop disassembly (Phillips and tri-wing), eyeglass repair (very small flat), appliance repair (PZ and Phillips), and furniture assembly (Robertson, which we included despite its Canadian origins because it shows up in imported furniture).
Criteria: tip-to-screw seating accuracy (how reliably the tip seats before the screw starts), cam-out resistance (how well the tip holds during sustained torque), tip durability (how many cycles before visible wear), and handle ergonomics at the end of a long session.
The Results: Tip Performance
Wera Lasertip: Consistently the best at initial seating. The laser-roughened tip surface genuinely grips the screw head — on recessed Phillips and PZ screws, you can feel the difference before you apply torque. Cam-out resistance was notably better than the other two conventional sets. After 200 cycles, the tip showed minimal visible wear compared to the Wiha and Facom.
Wiha: Solid performer. The tip geometry is slightly broader than the Wera — it fills the screw head well but on very worn screw heads (the recessed PZ screws in appliance repair, where the head is already partially stripped), it slips more than the Wera Lasertip. After 200 cycles: moderate tip wear visible, functionally still adequate.
PB Swiss: The tip geometry is machined to tighter tolerances than the others. On new or lightly-used screws, it's the most precise fit. On the damaged screw heads in our test, it performed closer to the Wiha than the Wera. The key differentiator is durability — after 200 cycles, the PB Swiss tip showed the least visible wear of any set. These are tools designed for professional use over years, not months.
Facom: The least precise tip geometry of the group. On small flat screws (eyeglass repair), it performed adequately. On PZ recessed screws, it cammed out noticeably earlier than the Wera or Wiha. The Facom is the best choice when grip texture on the handle is the priority — the tip is not the reason to buy this set.
The Results: Handle Ergonomics
Wera Kraftform Micro: The three-zone grip works exactly as described. Zone 1 (the rotating cap) allows fingertip spin for fine adjustments. Zone 2 (the wide bearing surface) transmits torque from the palm. Zone 3 (the tip grip) indexes the fingers for precision. After a 3-hour laptop disassembly session, the Wera was the most comfortable handle in the group. Your hand doesn't fight the tool.
Wiha: More cylindrical, more neutral. The grip is comfortable but the hand positions are less defined — you're placing your fingers rather than being guided to the correct position. At the end of a long session, the Wiha handle felt slightly less precise in positioning than the Wera. It remains comfortable throughout.
PB Swiss: The acetate handle has the least texture and the smoothest surface. In dry conditions with clean hands, it's perfectly adequate. With any moisture or oil, it becomes slippery. The handle diameter is slightly larger than the Wera and Wiha — this is either an advantage or disadvantage depending on hand size. In our testing with a range of testers, people with smaller hands found the PB Swiss less comfortable for precision work over extended periods.
Facom: The most aggressively textured handle. The rubber overmould over the cap provides excellent grip under torque. For furniture assembly — where you're applying higher torque over longer periods — the Facom handle is excellent. For precision micro-work, the aggressive texture becomes a disadvantage: it resists the finger-spin adjustments that precision work requires.
The Results: Durability
PB Swiss dominates here. After 200 screw cycles, the tips showed the least wear. The handles remain structurally sound with no degradation of the acetate. The PB Swiss tools we tested looked and performed like new at the end of the test period.
Wera second: Lasertip geometry held up well. Some surface finish wear on the laser-roughened area, but functionally the tip remained effective at cam-out resistance throughout the test.
Wiha: functional wear visible on tip, not yet affecting performance. Handle shows typical multi-component grip wear at the highest-contact zones.
Facom: tip wear is the most visible of the group at the same cycle count. The handle overmould shows compression marks at the torque zones.
The Verdict
Best for precision electronics (laptops, phones, watches): Wera Kraftform Micro. The Lasertip grip on recessed screws is a genuine functional advantage. The handle design guides your hand to correct positioning without training or conscious effort. At $75, it's the best value in this category.
Best for professional workshop use over years: PB Swiss. The durability is real, not marketing. These tools cost twice as much and will outlast three or four sets of budget tools. If you're buying precision screwdrivers as a professional investment rather than a household purchase, the PB Swiss is the correct choice. The handle grip is the only ergonomic compromise in dry conditions with clean hands.
Best for heavy appliance and furniture work: Facom. The aggressive handle texture and robust build quality handle the higher torque requirements of appliance repair and furniture assembly better than the precision-focused sets. The tip geometry is adequate for the task if not exceptional.
Best balanced option: Wiha. No single category winner, but no significant weakness either. A reliable set for the person who needs precision one day and heavier work the next.
The Budget Tier
For context: a $15 precision set from a hardware store performs adequately for one-time use. The tips are stamped rather than machined, so the geometry degrades faster. The handles are single-component plastic — functional but without the grip zones that make extended use comfortable. For occasional household tasks, these are fine. For anything approaching professional or regular use, the step up to Wera or Wiha is worth the cost difference within the first month of use.
