Stab-resistant armour and ballistic armour protect against different threats, and one type does not reliably protect against the other. Stab-resistant (and spike-resistant) armour is built to stop knives, edged blades and pointed weapons by spreading and resisting a sharp point. Ballistic armour is built to stop bullets and, depending on the level, fragmentation. The materials, construction and the standards they are tested to are different, so a vest rated only for knives should not be relied on to stop a bullet, and a soft ballistic vest may not stop a determined stab. If you face both risks, you need armour that is specifically rated for both, or layered protection that combines the two. Always check the manufacturer-stated protection level, and remember that ratings reflect standardised lab testing, not a guarantee in every real-world situation.
What is the difference between stab-resistant and ballistic armour?
The core difference is the threat each one is designed to defeat and the way it does so. They are engineered around different physics.
How stab-resistant armour works
A knife or spike concentrates force on a tiny point, so the armour has to stop that point from pushing through. Stab and spike-resistant panels typically use tightly woven, laminated or chainmail-style layers, and sometimes thin metallic or hard plates, to catch and spread the energy of a blade or a sharpened tool. Spike protection is a separate consideration from edged-blade protection, because a narrow spike behaves differently from a wide blade. Good stab armour is often rated for both edged blades and spikes.
How ballistic armour works
A bullet delivers a large amount of energy over a very short time. Soft ballistic armour uses many layers of high-performance fibre to catch a round, deform it and dissipate its energy across the panel. Hard armour plates use rigid materials such as ceramic or polyethylene composites to break up or stop higher-velocity rounds. The right approach depends entirely on the manufacturer-stated ballistic level you need.
Why does stab armour not stop bullets, and ballistic armour not always stop knives?
This is the single most important point for buyers, because assuming one covers the other can be a costly and dangerous mistake.
- A bullet is a high-energy, blunt-on-impact threat. Stab-resistant layers designed to grip and resist a blade edge are not built to absorb the energy of a fired round, so they should never be treated as bullet protection.
- A knife or spike is a focused, sharp threat. Some soft ballistic vests are woven to stop a deforming bullet but can still be penetrated by a narrow spike or a forced stab, because the fibres can be pushed apart by a fine point. This is why stab and spike resistance is tested separately.
- The test standards are different. Stab and ballistic armour are assessed against different standardised testing protocols. A product certified to a knife or spike standard has not been verified against bullets, and vice versa, unless the manufacturer states both.
In short, a rating only tells you about the threat it was tested against. Buy for the threats you actually face, and verify the manufacturer-stated levels rather than assuming broader coverage.
Stab-resistant vs ballistic armour: a quick comparison
Use this summary to orient yourself before you read the protection levels in detail. The exact materials and levels vary by manufacturer, so always confirm the stated rating on the specific product.
- Primary threat (stab/spike): knives, edged blades, pointed weapons and improvised spikes. Primary threat (ballistic): bullets and, at some levels, fragmentation.
- Typical construction (stab/spike): tightly woven and laminated fibre, chainmail-style layers, or thin plates. Typical construction (ballistic): multi-layer soft fibre packs and rigid hard plates.
- Weight and flexibility (stab/spike): often flexible and lower-profile for everyday wear. Weight and flexibility (ballistic): soft levels are wearable, hard plates add significant weight.
- Cross-protection: neither reliably covers the other unless the product is specifically dual-rated.
- Best for (stab/spike): roles facing edged-weapon and spike risk. Best for (ballistic): roles facing firearm risk.
What protection levels and standards should I look for?
Protection is described by levels set out in recognised testing standards. These levels are useful because they are based on standardised lab testing, which lets you compare products on a like-for-like basis. They are not a promise of safety in every scenario, because real incidents vary in angle, distance, weapon and force.
- Stab and spike levels describe how much force a panel resisted against a defined blade or spike in testing. Look for whether a product is rated for edged blades, spikes, or both.
- Ballistic levels describe which classes of ammunition a panel stopped in testing. Soft armour covers lower-energy threats, while hard plates are required for higher-velocity rounds.
When you read a product page, treat every level as manufacturer-stated and check it matches the threats you expect. If a vest lists only a stab rating, do not assume any ballistic capability, and the reverse is equally true.
How do I pick the right armour for my situation?
Choosing well comes down to honestly identifying the threats you face, then matching the rating, the fit and the wearability.
Step 1: Identify the threat
Decide whether your realistic risk is edged and pointed weapons, firearms, or both. If both are genuinely in play, look for dual-rated armour or a layered setup, and confirm each rating separately.
Step 2: Match the rated level
Pick the manufacturer-stated stab, spike or ballistic level that corresponds to your threat. Do not over-buy weight you cannot realistically wear, and do not under-buy a level below your actual risk.
Step 3: Choose the platform and fit
Soft panels can sit in a covert or overt carrier, while hard plates need a plate-rated carrier. Coverage and a correct fit matter as much as the rating, because armour only protects the area it covers. Browse ballistic vests and carriers and body armour panels and plates to match the level you need to a platform you will actually wear.
Step 4: Consider the full kit
Head protection is a separate decision from torso protection. If your risk profile calls for it, look at ballistic helmets and the relevant helmet accessories. For edged and pointed threats specifically, our stab and spike-resistant range and cut-resistant gear cover hands, arms and body where cuts and stabs are the main concern.
Can one vest protect against both knives and bullets?
Yes, but only if it is specifically built and rated for both. Some armour combines ballistic protection with a stab and spike-resistant layer or insert, so it is verified against both threat types. If a product does not clearly state both a ballistic level and a stab or spike level, you should assume it covers only the one it lists. Combining a ballistic vest with a separate stab or spike panel is another route, and it lets you tailor the protection to your specific risk.
Is it legal to own body armour in the UK?
Civilian ownership of body armour, including stab-resistant and ballistic armour, is legal in England, Wales and Scotland, and there is no licence required to own it. Laws differ by country, so if you are outside the UK or shipping internationally, you must verify what is legal where you live before ordering. R Supply Store does not provide legal advice, and it is the buyer's responsibility to confirm local legality.

Frequently asked questions
Does stab-resistant armour stop bullets?
No. Stab-resistant armour is tested against knives and spikes, not bullets, so it should not be relied on for ballistic protection. If you face a firearm risk, choose armour with a manufacturer-stated ballistic level.
Will a bulletproof vest stop a knife?
Not necessarily. We avoid the word bulletproof because no armour is invulnerable. Some soft ballistic vests can be penetrated by a narrow spike or a forced stab, because they are not designed to grip a sharp point. For knife and spike threats, use armour that is specifically stab and spike-rated.
What does manufacturer-stated protection level mean?
It means the level reflects standardised lab testing against a defined threat. It is a useful basis for comparing products, but it is not a guarantee of safety in every real situation, because angle, distance, weapon and force all vary in real incidents.
Can I buy body armour legally in the UK?
Yes. Owning body armour is legal for civilians in England, Wales and Scotland, with no licence required. If you are ordering from outside the UK, check your local law first, as rules differ by country. R Supply Store does not provide legal advice.
