Why a drop point
The default hunting and EDC shape, and the safest general answer. The spine curves down to the tip in a convex line, which keeps the point low and strong and leaves plenty of belly for skinning. It is hard to make a drop point bad at anything.
Every drop point here →About CPM-S35VN
S30V with niobium swapped in for some vanadium: slightly tougher, noticeably easier to sharpen, marginally less edge retention.
1-5 is a relative ranking drawn from published composition and hardness, not a lab measurement. Higher is better on every axis, and no steel is a 5 across the board — edge retention and toughness pull against each other. All CPM-S35VN knives
What owners say
Drawn from 272 owner discussions of the Cold Steel AD-10 since 2024. The opinions are theirs. The specifications above come from the maker.
What owners like
- The Tri-Ad lock is the headline. One owner who carries an AD-10 and AD-20 at a factory job has never had a hint of failure or blade play, another almost sold theirs but kept it because the lock turns it into a fixed blade with a snap, and a third reaches for it whenever lockup matters.
- Clean out of the box: one new drop point owner found an even bevel, a very sharp edge, a centered blade and smooth action, and another rates the fit, finish and centering ten out of ten with a grind better than some Spyderco and Benchmade knives they own.
- Built for jobs other knives should not do. A fieldworker whose Spydercos all have thin points carries it for the things you really should not do to a knife, a mail carrier uses it as the work knife, and other owners carry it for factory and general work and pull it out for tough, nasty cutting.
- Better ergonomics than its size suggests. One owner found the comfort good enough to push a Spyderco Shaman to second place for heavy use, and another says the rounded handle feels less bulky in hand than a Benchmade Adamas.
- Strong value on sale: one owner paid $70 in 2025 and says they would have been happy at $120, and another recalls paying about $100 for a large S35VN blade with an unquestionably solid lock.
- A favorite modding platform. Owners fit Original Goat aluminum or titanium scales, Snaggletooth, Rockscale and walnut scales, and swap the washers; one says the linerless scales made the knife feel much better and another found the rounded inside of the new scales made closing more comfortable.
- Slow-rolling it open is a pleasure to its fans: one owner calls it their fidget toy of choice and finds slow rolling it open satisfying, and another says Tri-Ad backlocks are more fun to play with than compression or button locks.
What owners flag
- Big and heavy for the pocket. One owner who loves theirs has never carried it because it is too big to lug around, and others admit it mostly sits in a drawer or is not really an everyday knife.
- The stock clip gets replaced. One owner says a new clip finally let them pocket it without tearing their pocket, another wants a better clip or a sheath, one swapped to a deep-carry clip and carries it more since, and another wants to replace the stock fat clip.
- It snaps shut hard near the fingers. One owner points out that the choil sits low enough for the heel of the edge to close where the index finger rests, and another cut a finger when it snapped closed sooner than expected.
- Action draws one unfavorable comparison: one owner found a $36 SR1 Lite had better action than their AD-10.
- Aftermarket scales take patience. Owners report waiting two to four months for Original Goat scales, and one found them out of stock for a long time.
- Cheap listings raise counterfeit questions: one buyer who paid $55 for one of many roughly $50 eBay listings received an M390 and carbon fiber version they could not find anywhere, and another asked for help confirming theirs was genuine.
A 3.5 inch S35VN blade, 6.8 oz and a Tri-Ad lock make the AD-10 the knife owners carry for jobs they would not trust to a slimmer folder. A fieldworker, a mail carrier and a factory worker carry it at work, and one factory owner reports no hint of lock failure or blade play.
Two new owners found theirs centered, sharp and smooth, one owner praises its comfort, and another found it less bulky than its reputation. The complaints are about carry and closing: one owner never carries it because of its size, several have replaced or want to replace the stock clip, and one knife user notes the low choil lets the heel of the edge close near the index finger. Owners rebuild it with Original Goat and other scales, one also swapping the washers, after waits of up to four months.
Benchmade Adamas, Spyderco Shaman and the Recon 1 are its usual rivals. One owner says the AD-10 feels less bulky than the Adamas, another moved it ahead of the Shaman for heavy use, and one knife user warns its weight may keep it from replacing a Recon 1. Owners paid $70 to $100, and one knife user puts it on par with much more expensive knives like the Shaman and Adamas.
Is the AD-10 too big to carry every day?
Owners split. One with a new drop point found it less bulky than its reputation and less blocky than an Adamas, while another has never carried theirs because it is too big. It has a 3.5 inch blade and weighs 6.8 oz in this configuration.
Why is the tanto version so often cheaper?
Retailer sales: one owner bought the tanto for $75 in a Midway sale in 2025, and knife users that year quoted about $70 for the S35VN tanto there, while one buyer who preferred the drop point waited a long time for it to go on sale. One owner later added a drop point to go with their tanto.
Which aftermarket scales fit the AD-10?
Original Goat linerless aluminum and titanium scales are the ones owners mention most, with waits of two to four months. Others have fitted Snaggletooth, Rockscale, Knathan's Knives and walnut scales.
Is the titanium and 3V AD-10 worth it over the G-10 version?
Owners of the titanium sprint runs say it is smoother and thinner than the G-10 knife, one calls the action like glass, and one hardness test put a 3V AD-10 at 59.3 HRC. The page covers the G-10 and S35VN version, and one owner points out the titanium version weighs about 9 oz.
Is a $50 AD-10 on eBay genuine?
One buyer who paid $55 for one of many listings around $50 received an M390 and carbon fiber combination they could not find anywhere online, and asked whether it was a counterfeit. One owner paid $70 in a retailer sale, and another knife user says sales around $80 come up.
